Regardless, configuring without arguments should build a usable compiler.

The rules to build libgcc_s.so are chosen during configure, which always
chooses solaris ld unless --with-ld or --with-gnu-ld are given.
However the gcc driver first checks in ${prefix} for binutils.  If found,
the build fails on SHLIB_LINK.

This problem may probably worsen as more target-specific t-slibgcc-*
rules appear.  Perhaps it would be better if libgcc_s were configured
after the stage1 compiler is built so the correct ld could easily be
determined.  (For that matter, libtool could replace much of the
t-slibgcc-* mess if this were so.)

The workaround is to always specify --with-ld and/or --with-gnu-ld when
configuring on solaris.
