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,
 [2] setcontext deprecated on x86,

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.
