Fix the microblaze syscall interface.
Recent mainline kernels no longer carry userland code to invoke syscalls
and microblaze can use the uClibc generic code.

Rework crt bootstrap to work with the new __uClibc_main(),
and hardwire crt init/fini code since the awk approach to generating it on
the fly doesn't work for microblaze. The output from the gcc 4.1.2 compiler
is scrambled so that the tags expected by the awk script to bracket the
init/fini entry and exit code no longer do.

An architecture that _may_ have a MMU (and thus implements
the msync syscall), but for which the kernel and uClibc are built as
noMMU, we have a stub for msync.
Thanks to Steven J. Magnani for noticing.

If there was an error during syscall then after it's completion a3
register holds a non-zero value and v0 holds an actual error code which
should be saved in errno. This can be achieved by calling
__syscall_error with the value from v0 as a parameter. So this value
should be stored in a0, but the appropriate assembly instructions are
missing. Fixed this now by adding "move a0, v0".
I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07
but then something went wrong. Again...

NPTL library needs both madvise and statfs symbols, that are guarded
by UCLIBC_LINUX_SPECIFIC option. This fix provides these symbols too
when NPTL is used, indipendently by UCLIBC_LINUX_SPECIFIC choice.
Otherwise libpthread link fails as below:
LD libpthread-0.9.32-git.so

cancellation points : waitid, sleep, fdatasync, ppoll.
Further, if generic syscall is not available and stubs are
configured, provide the stub implementation for function.

Indeed unistd.h header does export '__getpgid' by default, while
uClibc provide only 'getpgid' implementation. The 'getpgid' symbol
is exported by standard header if __USE_XOPEN_EXTENDED is defined.
This patch alignes uClibc implementation with standard header (matching
with glibc behaviour).

The rpc rcmd code has some ugly ifdef mazes to handle mmu/nommu differences
just to select alloca or malloc. Unify those with some helper macros in a
new header, and then convert the rcmd code over to it.
This is all geared towards fixing the getdents helper functions which only
use alloca() atm. Now that we have helper functions, convert the getdents
functions over too.

Closes #2089 (https://bugs.busybox.net/show_bug.cgi?id=2089)
__errno_location / __h_errno_location access has to go through the PLT
like malloc/free, so the linuxthread variants gets used instead when
compiling with -pthread.

The MIPS specific INLINE_SYSCALL macro has been renamed to
INLINE_SYSCALL_NCS with:
763bbf9e9a27426c9be8322dca5ddf2cb4dbc464
syscall: unify part 2: NCS variety
Declare common NCS (non-constant syscall) variants and convert the
existing ports over to this.
This change breaks system calls. The code generated with using of the
new macro does not obey the restartable syscall convention used by the
linux kernel. When it tries to restart the syscall the errno value is
not being replaced by the syscall number.
This causes weird behaviour of the 'ping' command in busybox for
example:
root@OpenWrt:/# ping 192.168.1.254
