Subject: fix jmp_buf size on armhf
On armhf (!__SOFTFP__) with __ARM_ARCH__ >= 6 and __ARM_NEON__,
sigsetjmp() can store as much as 42 registers:
* d0 - d15 (armhf) => 16
* d16 - d31 (NEON) => 16
* r4 - r11, sp, lr => 10
Make appropriate space for that in jmp_buf and remove an unused
define at the same time.
