KLUDGE/workaround for ICE

I worked around the ICE on AIX with this patch.  THIS IS A WORKAROUND ONLY--I
do not know the code anywhere near well enough to believe this is a correct
fix.

It changes tree-emutls.c so that a weak symbol remains public, which then lets
it go through the assert in ipa.c.
