Yousong Zhou ef7aa03bdb libunwind: bump to version 1.3.1
Libunwind provides a sigreturn stub for x86 in version 1.2 [1].  However
the arch still depends on setcontext() which is unavailable in musl-libc
and which is supposed to be "deprecated everywhere" [2]

 [1] x86 sigreturn unimplemented for some libcs,
     https://github.com/libunwind/libunwind/issues/13
 [2] setcontext deprecated on x86,
     https://github.com/libunwind/libunwind/issues/69

Yousong Zhou 1e5f4dcd66 libunwind: requires glibc if arch in powerpc
libunwind for powerpc depends on getcontext() from libc which musl-libc
does not provide because this API and its friends are supposed to be
"obsolescent" [1,2]

Jo-Philipp Wich 0e70f69a35 treewide: revise library packaging
- Annotate versionless libraries (such as libubox, libuci etc.) with a fixed
  ABI_VERSION resembling the source date of the last incompatible change
- Annotate packages shipping versioned library objects with ABI_VERSION
- Stop shipping unversioned library symlinks for packages with ABI_VERSION

libunwind: fix build with musl on PPC
Works around two incompatiblities between glibc and (POSIX-compliant) musl:

- missing register definitions from asm/ptrace.h
- non-POSIX-compliant ucontext_t on PPC32 with glibc

Compile tested on mpc85xx.

Yousong Zhou f0c37f6ceb libunwind: disable building with ssp
If we enable -fstack-protector while building libunwind, function
__stack_chk_fail_local will be referred to for i386 and powerpc32
arches.  This will cause link failure because the default gcc build
specs says no link_ssp if -nostdlib is given.

The error message:
