Subject: [PATCH] mips/setjmp.S: don't save and restore floating-point
 registers

Klibc FTBFS with '-mno-odd-spreg' on mips32(el) platforms,
As it try to save/restore odd-number FPR.

Indeed no other architectures save/restore FPR at all.
It shouldn't be needed.

Gbp-Pq: Name klibc-mips-setjmp-s-don-t-save-and-restore-floating-point.patch
