With glibc 2.26 'struct ucontext' is removed to improve POSIX
compliance, which breaks powerpc/alignment_handler selftest. Fix the
test by using ucontext_t. Tested on ppc, works with older glibc
versions as well.
Fixes the following:
alignment_handler.c: In function ‘sighandler’:
alignment_handler.c:68:5: error: dereferencing pointer to incomplete type ‘struct ucontext’
ucp->uc_mcontext.gp_regs[PT_NIP] += 4;
