Besides, because GCC on Solaris supports two incompatible versions of ld
(Solaris ld and GNU ld), it is crucial to specify the path to the linker
you want to configure with with --with-ld=<path to ld> (both for
/usr/ccs/bin/ld and some version of GNU ld).  Otherwise, PATH changes
would randomly break the resulting gcc.

If you really want to use GNU ld (I don't know why you would, though),
please build and use a recent one: at least what's recommended in
install.texi.  You'd probably be able to use GNU ld from current
binutils 2.38, too.

On top of that, I wouldn't bother with GCC 3.4 at all.  Instead, please
use the latest release still supporting Solaris 9, GCC 4.9.4 It's way
better tested and supported than the ancient GCC 3.4.  Please consult
the Solaris sections of the bundled install docs in
gcc/doc/install.texi.  It contains many hints and caveats to consider
when building GCC.  The online version on gcc.gnu.org is for GCC trunk
only: everything pertaining to Solaris versions no longer supported
(i.e. before Solaris 11.3) has been removed.
