More than "likely" I think.  I'm using a unified CVS gcc + CVS binutils
source tree, and the patch below causes serious breakage to anything linked
against libstdc++.  We get a SEGV when exit() calls some of the dtors in
the library.

After reverting this patch I can once again run hello-world on i686.

WRT a configure-time check... we (lib-3) had to do something similar for
the compiler itself at one point.  If the date on which the linkonce bug in
ld was fixed can be pinpointed, perhaps a check for a sufficiently recent
version is enough.
