Patch: +28 -2
 - include <asm/sgidefs.h> from linux-headers;
 - pass something that musl recognizes as a valid sigprocmask 'how'
   parameter to prevent early exit due to EINVAL; SIG_BLOCK is zero
   on non-mips* (wrt to Alpine's set of architectures) so all other
   targets should be unaffected.

The SIG_BLOCK patch should be dropped when proper musl fix appears.
