Linux does usually have a link from gcc to cc, but Linux also usually has
some sort of package management like RPM. So being a careful installer I
removed gcc with rpm -e gcc  (which also removes the symlink, headers,
etc.) and installed egcs with make install. Upgraded to the next egcs
snapshot and voila, my ppclibc1 stuff was no longer working. Took me quite
a while til I noticed what was happening ;-).
