[PATCH] Determine libgcc_s version

[Roland McGrath]

I'm not at all sure we really want to do this via configure.  This is the
ambient ABI requirement we are building into the libc we build, a bit like
the --enable-kernel setting.  It seems to me we might only want that to
change by conscious choice, not by implicit magic.  I guess that would just
mean maintaining it manually in shlib-versions.  That seems wiser to me off
hand.  But I don't know what Jakub or Uli think about it, and I'm happy to
defer to the consensus.


Thanks,
Roland
