>Description:
	gcse on mipseb (and possibly mipsel?) miscompiles libc/gen/execle.c such
	that getty can no longer spawn login.  I suspect that it may have
	something to do with the varargs voodoo therein.  Other exec*.c with
	similar logic may also be affected.  -fno-gcse-lm does not fix the
	problem, but -fno-gcse does.
>How-To-Repeat:
	Compile libc/gen/execle.c with gcc-3.3.1.  Watch it fail.
>Fix:
	Workaround is -fno-gcse.
