MFC r287292:
Switch libc from using _sig{procmask,action,suspend} symbols, which
are aliases for the syscall stubs and are plt-interposed, to the
libc-private aliases of internally interposed sigprocmask() etc.
MFC r287300:
Use libthr interposed functions instead of syscalls, in posix_spawn()'
child.
