3.4 PATCH: Fully support GNU linker in libtool on IRIX 5/6

[Rainer Orth <ro at TechFak dot Uni-Bielefeld dot DE>]

I recently tried to bootstrap mainline on IRIX 6.5 with GNU as and ld
2.14.90 (i.e. binutils mainline).  The compiler bootstrapped ok, but
building libstdc++ originally failed:

xgcc: libstdc++.so.7: No such file or directory
xgcc: sgi7.0: No such file or directory
xgcc: unrecognized option `-soname'
xgcc: unrecognized option `-set_version'
make[4]: *** [libstdc++.la] Error 1

This error happened for a couple of reasons: the gcc and g++ drivers don't
recognize the -soname and -set_version options, unlike SGI's cc.  They need
to be prefixed with -Wl, to work.  Even after that change, GNU ld doesn't
recognize -set_version or -update_registry.

The following patch (created with -b so the indentation differences don't
obscure the proper content) fixes this and allowed a bootstrap to finish.
Testsuite results are still terrible, though: many tests (primarily c++ and
objc) time out or abort in __deregister_frame_info_bases.  I'll have to
investigate what's going on there (but with a low priority; I was just
trying to find out if/how well GNU ld works for the N32 and N64 ABIs before
trying to determine why it cannot link shared libraries for O32).

Ok for mainline?

	* ltcf-c.sh (irix5*, irix6*): Handle GNU ld: prefix -soname and
	its arg with ${wl}, omit -set_version, -update_registry.
	* ltcf-gcj.sh (irix5*, irix6*): Likewise.
	* ltcf-cxx.sh (irix5*, irix6*): Prefix -soname and its arg with
	${wl}, omit -set_version with GNU ld.
