the last half-sentence about memory corruption: no details, no PR or

Although the bugs seem to be easily fixed Besides, breakage wide into the
bootstraps seems like a poor way to convey that information ;-)

My change needs to be tested with both Sun ld and GNU ld since the
inclusion of gcc/config/i386/t-crtstuff will become conditional upon a link
test, and I need to test all paths: older/broken Sun ld, new/fixed Sun ld
and GNU ld. And for the GNU ld case (which I've not tried in a long time
if at all) I need a baseline without my change.
