[Bug c/33598] New: gcc 4.2.1 ignores GNU LD in Solaris 9

["dhaliK at jla dot rutgers dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

We recently upgraded to 4.2.1 and noticed an immediate issue. After compiling
gcc for sparcv9 and specifically setting --with-ld=/usr/local/gnu/bin/ld,
whenever gcc actually runs it internally calls the Sun linker and therefore
dies with unknown options. A simple "hello world" refuses to build because of
bad LD options. Setting LD= seems to have little effect. I'm pasting a -v
output of it below. Note I was using g++ here because that was handy, but it is
the same for eitehr gcc or g++:

/usr/local/bin/sparcv9/g++ -v hello.cpp   
Using built-in specs.
