Really? There's nothing suggesting so in:
http://gcc.gnu.org/viewcvs/trunk/gcc/doc/install.texi?revision=168202&content-type=text%2Fplain&view=co

In there, only --enable-gold is documented. Or I can't read texi. :-)

If you looked at ./configure and saw the same options as for binutils, then
do not be confused. Those GNU guys use a shared (templated?) ./configure, so
you may got mislead...

What I understood is:
 1) --enable-gold is available starting with gcc-4.5, and 4.6 did not change
 3) --enable-gold does nothing by itself
 4) --enable-gold with --enable-lto builds a plugin that gold can use to
    handle LTO
 5) there's no 2)
