My intention was to get rid of uClibc_mutex.h completely on install, but it
introduces other dependencies. It affects anyway only the installed case.
Note: since NPTL was added, the FILE structure changes between the build
and the installed version. I wanted to fix this by the earlier commit.
Reverting the behaviour to IMHO a wrong one.
While there, remove libc-lock.h and stdio-lock.h on install (even though
glibc has them -wrongly- installed).

Make sure we use the new jmpbuf-*.h headers
While there, adapt the offset on microblaze and the _JMPBUF_UNWINDS macro on bfin,
it seems, these were changed in the meantime.

Currently, the installed libubacktrace linker script entry always uses
HARDWIRED_ABSPATH semantics, even if HARDWIRED_ABSPATH is disabled:
$ grep GROUP $PREFIX/mipsel-linux-uclibc/sys-root/usr/lib/libc.so
GROUP ( libc.so.0 uclibc_nonshared.a AS_NEEDED ( ld-uClibc.so.0 ) )
GROUP ( AS_NEEDED ( /lib/libubacktrace.so.0 ) )
This causes problems when building a non-sysroot toolchain.
Move the AS_NEEDED insertion into libc/Makefile.in, and add a case to
the HARDWIRED_ABSPATH substitution command so libubacktrace is handled
the same way as the other libraries listed in the script.

glibc has split off the arch-specific flag definitions (like
SFD_NONBLOCK) into <arch>/bits/signalfd.h, so that there are no longer
multiple redundant copies of the entire header file. We will adopt the
same scheme in uClibc.
Special cases are included for: alpha mips sparc
hppa was omitted because it has not been updated in glibc.
All others use the common definition.

Since we want to clean out all the headers we symlinked into include/,
just use `find` to locate all the symlinks for us. This simplifies it
greatly, and actually fixes bugs where we build for one arch, switch
to another, and then do a clean but the previous arch headers are left
behind.

Don't rely on argument-shuffling but use correct arguments in
the first place.
In bug#3589 Thomas Suckow writes:
The modified kconfig defines -D to be the same function as -d. In
addition -d does not take an argument and Config.in should be passed as
a non-option argument. The existing argument order appears to work on
distributions such as Fedora but chokes on Cygwin (newlib?).

When NPTL is not enabled, and LOCALE support is used, compilation fails
with the following error:
-------------------------------------------------------------------------
MKDIR include/bits
GEN include/bits/sysnum.h
make[1]: *** No rule to make target `../..//include/bits/uClibc_ctype.h', needed by `../../extra/locale/gen_wc8bit.c'. Stop.
make: *** [pregen] Error 2
-------------------------------------------------------------------------
The problem is that "headers" is not listed as prerequisite of pregen.
These have been changed multiple times recently:
o Austin: order headers before pregen-headers

o Khem: pregen: Fix the parallel build problem in pregen target

o Khem: pregen-headers: Add new target which depends on headers.
ef18cfe8ebab25f5ef92e81956f50e2dc57df602
o Carmelo: build: Fix infinite loop when no threading support is enabled
ff5e4de7088fe8d34812c2a1e604bf04be713606
In all of these commits headers was actually as prerequisite
In commit 9381d622e2411a35a5fd73a5a573eb269e2dd9c9 [nptl: fix buildsys] by Bernhard, headers was removed,
causing the problem reported above.

The generation of the sysnum.h has to be a prerequisite of
'pregen' target instead of headers, because it needs the compiler
already available.
The so called C bootstrap headers are required to build the compiler
by invoking 'make headers', so the 'headers' target cannot relies itself
on the compiler to be invoked.

According to git man page the syntax for git archive should have
the <tree-ish> as last argument. Indeed using git 1.5.5.6 the tarball
was not properly created. Newer version (i.e. 1.6.3.3) works fine even if
HEAD comes before other option. For backward compatibility use a syntax
that is fine with older git.

The respective source has to depend on a given set of headers.
Depending all on headers is papering over an eventual missing other
dependency, so reverting.

A new shared object, libubacktrace.so.0 is added to uClibc
to provide backtrace functions to support application self-debugging.
This set of functions requires to dynamically load libgcc_s.so so they
need to call dlopen/dlsym that are provided by libdl. For this reason
they cannot be included into libc.so.0 but are provided by a new library.
User application that wants to use backtrace needs to be compiled with
-fexceptions option and -rdynamic to get full symbols printed and must be
linked against libubacktrace.so
