egcs-970904: Misbehaviour calling as with -b -V

[Jim Wilson]

	This is the result of 'gcc -b i586-linuxlibc1 -V 2.7.2.2.f.2 -c tst.c':

	 as -V 2.7.2.2.f.2 -Qy -o tst.o /tmp/cca05227.s
	GNU assembler version 2.8.1 (i586-linux), using BFD version linux-2.8.1.0.1
	Assembler messages:
	Error: Can't open 2.7.2.2.f.2 for reading.

This is a bug in gcc 2.7.2.  The ASM_SPEC says that any -V option on the 
command line should be passed to the assembler, which is wrong, because gcc -V
is something completely different than as -V.  This is fixed in EGCS.

You are seeing the bug because you use the -V option to specify 2.7.2,
which caused the 2.7.2 specs file to be read in.  If you fix the 2.7.2
specs file, then the problem will go away.
