eclass/tests/toolchain-funcs.sh: fix gold tests, bug #700812

As written tests assumed that $CC always called ld.bfd as a linker.

The assumption fails when default linker is not ld.bfd,
(for example sys-devel/binutils[default-gold]).

The change uses LDFLAGS=-fuse-ld=bfd explicitly.

Fixes the following tests:
 * Testing tc-ld-is-gold (bfd selected) ...       [ !! ]
 * Testing tc-ld-disable-gold (bfd selected) ...  [ !! ]
