An all-in-one patch that fixes several issues:
1) no sys/platform/ppc.h outside of glibc (disabled on musl)
2) generic stacktrace implementation only works on glibc (disabled on musl)
3) powerpc stacktrace implementation only works on glibc (disabled on musl)
4) powerpc stacktrace implementation has ppc64 assumptions (fixed)
5) examine_stack.cpp makes glibc assumptions on powerpc (fixed)
