Mips patch to honor -mfp32

[Michael Meissner]

The GCC patch I submitted last night now defines __mips_fpr to be the
fpr register size on MIPS, and this patch that I committed honors
that.

2001-09-11  Michael Meissner  <meissner@redhat.com>

	* mips/crt0.S (_start): If -mfp32, don't enable 64-bit floating
	point registers, even if we are compiling for a mips3 or greater.
