Follow the steps to build c-sky uclibc linux system:
1. git clone https://github.com/c-sky/buildroot.git
2. cd buildroot
3. make qemu_csky_ck810_uclibc_defconfig
4. make
Follow the buildroot/board/qemu/csky/readme.txt to run.
This buildroot toolchain is pre-build, But you can rebuild
the c-sky uclibc-ng alone and install it to the buildroot
sysroot manually.
We'll try our best to improve the uclibc-ng continuously.

The current uclibc-ng use 4 arguments, and this will cause
ltp-testsuite's preadv/pwritev case failed.
The syscall of preadv/pwritev in current linux-kernel is 5 arguments:
linux/fs/read_write.c:
SYSCALL_DEFINE5(preadv, unsigned long, fd, const struct iovec __user *, vec,
unsigned long, vlen, unsigned long, pos_l, unsigned long, pos_h)
SYSCALL_DEFINE5(pwritev, unsigned long, fd, const struct iovec __user *, vec,
unsigned long, vlen, unsigned long, pos_l, unsigned long, pos_h)
So just update to 5-args-syscall, and off_t could be 32bit or 64bit.

The function towlower doesn't work with locales different from C.
Issue was introduced in commit: 8cde3a9bf2856dcb9a759dec7ecb04a68e712254
Call to setlocale is needed for correct generation of the table uplow_diff.
Otherwise you receive compile time error "range assumption error" after
uncommenting the call.
Similar problem described here:
http://lists.uclibc.org/pipermail/uclibc/2015-March/048852.html
This commit fix the problem by using int32_t values.

This commit includes following features.
1. Support NPTL/TLS
2. Add libm function which is used to handle FP rounding and excpetions
(ex: fclrexcpt,fedisblxcpti,feenablxcpt... )
3. Add *context function for operating user context
(ex: setcontext,getcontext,makecontext... )
4. Change the return flow from signal handler
5. Cleanup of old code
The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1,
which are related to timing accuracy. (math and locale tests are disabled)

Similar to musl libc a single libc has many benefits and solves
some open issues with uClibc-ng.
- no pthread_mutex_* weak symbols exported anymore
- applications no longer failing to link when either
-lrt or -lpthread are missing for dynamic and static linking mode
- smaller C library
- slightly better runtime performance

Commit 251a3c19cb "sleep: employ __USE_EXTERN_INLINES (with necessary fixes)"
introduces following problems:
1. __USE_EXTERN_INLINES forcibly enabled build fails
...

...
2. libuargp wrongly contains __cmsg_nxthdr/__sigismember/__sigdelset/__sigaddset
global symbols on platforms which includes signal.h from sys/procfs.h
As result, static linking will fail:

We have to partially revert 251a3c19cb to fix problems above. It is
safe to do this after commit
162cfaea20 *: inline constant __sig{add,del}set and __sigismember

rest of world(__USE_EXTERN_INLINES) equal to glibc now.

Linuxthreads.new isn't really useful with the existence
of NPTL/TLS for well supported architectures. There is no
reason to use LT.new for ARM/MIPS or other architectures
supporting NPTL/TLS. It is not available for noMMU architectures
like Blackfin or FR-V. To simplify the live of the few uClibc-ng
developers, LT.new is removed and LT.old is renamed to LT.

On systems where uClibc doesn't provide an arch specific byteswap.h,
we fall back on bits/byteswap-common.h. However, there is a bug
in this header in the __bswap_constant_64(x) macro. If, for example,
a double is passed, we get 'invalid operands to binary &' in which we
mismatch a 'double' and 'long long unsigned int'. The newer glibc
headers fix this and so we import them. Also, since the inclusion of
byteswap.h is not appropriate for assembly code, we guard a portion
of endian.h which uses byteswap.h from inclusion in any assembly.
This is needed, for example, for f2fs-tools 1.6.0 on 32-bit big
endian PowerPC.

Argp is an advanced support for parsing unix-style argument vectors.
In addition to the common getopt interface, it provides automatic
response
to `--help' and `--version' options and use of custom parser in
conjunction
with argp native option parser, among others.
Argp support is required by elfutils package and prelink.
In uClibc argp functionalities has been moved from C library to
libuargp.so
Further the libc.so linker script contains an AS_NEEDED entry so that
it doesn't need to link libuargp.so explicitely.
Disable argp test if feature disabled.

Commit e3c3bf2b58 introduce use of pselect6, but has following disadvantages:
* Use of userspace types in args67 structure - it breaks, for example,
configs when 32-bit uClibc-ng compiled against 64-bit kernel. Syscall
will always return EINVAL. We must use __kernel_* types and
__SYSCALL_SIGSET_T_SIZE.
* It have excess checks for NSEC_PER_SEC. Original code from select()
implementation has struct timeval => struct timespec conversion,
kernel select() syscall implementation do the same.
But none of libc versions (glibc, eglibc, musl) I know, perform similar
checks for pselect() - there is no structure fields conversions,
just struct timespec through all the calls.
To have such checks in uClibc-ng we need one example, at least.
* It is possible to avoid extra userspace reads from kernel code if
sigmask == NULL. I suggest to do it, for a few bytes cost.
* Commit didn't add test case to testsuite.

Linux has a pselect syscall since 2.6.something. Using it
rather than emulating it with sigprocmask+select+sigprocmask
is smaller code, and works properly. (The emulation has
race conditions when unblocked signals arrive before or
after the select)
The tv.nsec >= 1E9 handling comes from uclibc's linux select()
implementation, which itself uses pselect() internally if the
pselect syscall exists. I though it would be good to do the
same here.
Note that although the libc pselect() API has 6 arguments,
the linux kernel syscall as 7 arguments. There is an extra,
somewhat vestigial, sizeof the signal mask argument.
