Provide common prototypes for __longjmp, __libc_longjmp, __libc_siglongjmp
_longjmp_unwind, __libc_unwind_longjmp in setjmp.h in preparation for use in LT new
Add __longjmp to h8300 and i960
Make common longjmp.c good for NPTL
Guard _longjmp_unwind use in sh's longjmp.c for NPTL (I think sh could use the common one)
Remove unneeded attribute_noreturn, prototype provides it already

Do not pollute libraries with its own implementation of __aeabi_unwind_cpp_pr1 code.
Just add it to uclibc_nonshared.a archive and share it.
This fixes build issue with static linking of application due to multiple symbol
definition in libgcc_eh-a and libpthread.a or librt.a

If backtrace support is turned on, build raise() and abort() with
unwind info (fixup 4c9b7f3c21ff21c199e54bfad2fdf3445fa4573d).

Build raise and abort function with dwarf2 info by using
-fasynchronous-unwind-tables to make backtrace() working across a
call to abort.
A scenario where it could be useful is within a signal handler that
wants to dump a backtrace when catching some signal (i.e SIGABRT).
Without having abort & raise built with DWARF2 information, it is not
possible for the libgcc stack unwinder to walk through the call stack
out of the abort/raise function.
Impacts in terms of size are really limited

ARM disables by default the support for ASM CFI directives.
Anyway using an old version of binutils that does not support some new
pseudo-op, the build fails as below:
AS libpthread/nptl/sysdeps/unix/sysv/linux/close.oS
libpthread/nptl/sysdeps/unix/sysv/linux/close.S: Assembler messages:
libpthread/nptl/sysdeps/unix/sysv/linux/close.S:9: Error: unknown pseudo-op: `.cfi_sections'
The problem is that the .cfi_sections pseudo should be wrapped by a macro
that expands to nothing when the CFI is off.

My change a49b3a18e463cbe8c94c41501e386e7f4c61609e fixed two
Unwind_Resume calls to go via PLT to avoid text relocations for PIC
builds. However, it looks the reason for upstream not using PLT calls
is that ebx gets clobbered. So we need to reload it.

The SSP_ALL_CFLAGS in nptl arch CFLAGS leaks out and forces things
like dl-support.c, brk.c, sbrk.c memcpy, etc to be built with
-fstack-protector-all. This is bad when linking statically since
initializing TLS will call those functions before SSP is initialized.
The libpthread itself will still be built with -fstack-protector-all
due to CFLAGS-nptl has SSP_ALL_CFLAGS in libpthread/nptl/Makefile.in
Thanks to Timo Teras for helping with this.

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...
