debloat jmp_buf in _GNU_SOURCE mode
i originally made it the same size as the bloated GNU version, which contains space for saved signal mask, but this makes some structures containing jmp_buf become much larger for no benefit. we will never use the signal mask field with plain setjmp; sigsetjmp serves that purpose.
