[PATCH] fix use of 'if !' in shell script inld/emultempl/elf32.em

[cgd@broadcom.com]

When building for target mips-elf (and probably others 8-) on host
sparc-solaris (solaris 2.6, 7 and 8, at least), the generation of the
ld scripts chokes with:

/bin/sh ../../src/ld/genscripts.sh ../../src/ld /usr/local/lib /usr/local sparc-sun-solaris2.7 mips-mips-elf mips-elf "elf32ebmip" "/usr/ccs/lib" elf32ebmip "mips-elf"
../../src/ld/genscripts.sh: !: not found

(Actually, it produces that error message and continues on.  That's
kind-of concerning, too, but i'm going to delcare it SEP for now.  8-)

Anyway, the code currently does:

	if ! cmp -s ....; then

The 'if !' construct is not supported by the Solaris /bin/sh.  (*sigh*)


If i hear no objections about the following, I'll check it in tonight
or tomorrow morning.  ("obvious and trivial."  8-)

Tested by building for target mips-elf on host sparc-solaris.  Error
message went away.  No unexpected failures from 'make check'.
