Since librt and libpthread are now integrated into libc, including
unwind-resume and unwind-forcedunwind implementations of unwind code
makes no sense. Only unwind-forcedunwind is now included with
functions hidden to avoid them overriding the ones from libgcc_s.
* libpthread/nptl/sysdeps/generic/unwind-resume.h: New. Define
generic PERSONALITY_PROTO and PERSONALITY_ARGS and set
HAVE_ARCH_UNWIND_RESUME to 0.
* libpthread/nptl/sysdeps/pthread/unwind-resume.c: Move...
* libpthread/nptl/sysdeps/generic/unwind-resume.c: ... here. Include
generic implementation of _Unwind_Resume on the condition that
!HAVE_ARCH_UNWIND_RESUME. Make functions hidden to prevent them
from overriding libgcc_s's ones.
* libpthread/nptl/sysdeps/pthread/unwind-forcedunwind.c: Likewise.
* libpthread/nptl/sysdeps/arm/unwind-resume.h: New. Define
ARM-specific PERSONALITY_PROTO and PERSONALITY_ARGS and set
HAVE_ARCH_UNWIND_RESUME to 1.
* libpthread/nptl/sysdeps/arm/arm-unwind-resume.c,
* libpthread/nptl/sysdeps/arm/pt-arm-unwind-resume.c,
* libpthread/nptl/sysdeps/arm/rt-arm-unwind-resume.c: New.
ARM-specific implementations of _Unwind_Resume resp. for libc,
libpthread and librt.
* libpthread/nptl/sysdeps/Makefile.commonarch: Remove both
arm-unwind-resume and rt-arm-unwind-resume from
libpthread_arch_CSRC.
* libpthread/nptl/sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c,
* libpthread/nptl/sysdeps/unix/sysv/linux/arm/unwind-resume.c: Remove.

When built with gcc 5.1, uClibc-ng fails to build with the following
issue:
librt/librt_so.a(rt-unwind-resume.oS): In function `_Unwind_Resume':
rt-unwind-resume.c:(.text+0x3c): undefined reference to
This commit fixes the code in a way similar to what was done in glibc

This matches a similar change made to glibc.
No functional changes here.

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.
