Fix the following musl build failure with powerpc raised since bump to
version 2.14 in commit c6addf4606:
In file included from fault.h:36,

from handler.c:19:
handler-unix.c: In function 'sigsegv_handler':
fault-linux-powerpc.h:35:73: error: 'mcontext_t' has no member named 'uc_regs'; did you mean 'gregs'?
35 | # define SIGSEGV_FAULT_STACKPOINTER ((ucontext_t *) ucp)->uc_mcontext.uc_regs->gregs[1]
| ^~~~~~~
handler-unix.c:157:43: note: in expansion of macro 'SIGSEGV_FAULT_STACKPOINTER'
157 | uintptr_t old_sp = (uintptr_t) (SIGSEGV_FAULT_STACKPOINTER);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
