in general, SOLARIS should use /usr/bin/ld.

Make equivalent to unxgcc.mk (with gld).
NB: use $(READELF) updated in configure.ac and config_host.mk.in

(cherry picked from commit d6afd367)

Conflicts:
	solenv/gbuild/platform/solaris.mk

note: while cherry-picking to master, removed all mention of toolchains
that are unsupported on master due to lack of C++11 support (GCC < 4.6).
