bootstrap/5187: gcc 3.0.3 fails to bootstrap on Sun Ultra 60with Solaris 8

This @target_alias@ is the *real* problem, IMHO.

Most evidently, it does'nt get expanded to the proper target name (sparc-sun-solaris2.8). This
is *very* bad.

Which version of autoconf are you using? Perhaps 2.50? In that case, downgrade to 2.13 and
everything should be ok.

Cheers,
Paolo.
