libunwind: fix build with musl on PPC

2018-02-25T15:58:10+00:00

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.

libunwind: disable building with ssp

2017-11-06T02:49:58+00:00

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:
