Reverted r286451 "[ELF] - Allow separate form for -f (alias for -auxiliary)."

Though the patch was technically correct,
the only FreeBSD port (noticed atm) that tried using it was
www/mod_jk. And it seems just passed gcc option to linker by mistake:

"-Wl,-L-L/usr/local/lib -Wl,-rpath,/usr/local/lib -Wl,-fstack-protector -Wl,-fstack-protector -o mod_jk.la "

Given that it is an easy mistake to make, reverting for now.
