* mips-tdep.c (mips_push_arguments): Tweak alignment of register

Browse Source 
value if the remaining length of a non-integral argument is smaller
	than the register size for big-endian non-EABI mode.

	* rs6000-tdep.c (branch_dest):  Handle return from signal
	handler function via sigreturn kernel call.
