PATCH: PR gold/14897: gold is installed as default ld by accident

["H.J. Lu" <hongjiu dot lu at intel dot com>]

Hi,

We should install gold as default ld only for --disable-ld or
--enable-gold=default.  Tested with

--enable-gold
--enable-gold=default
--enable-gold --disable-ld

OK for trunk and 2.23?

Thanks.

H.J.
