building gcc 4.0.0 on Solaris

OK, I guess the latest compilers from Sun ship with a better "as".
Unfortunately I'm stuck with Sun Studio One 7 for now. Maybe it should
be documented that a recent version of "as" is needed by gcc.

Oh, I don't know how I missed that, sorry. I guess I was looking for the
error message, not for the solution.

Maybe I'm misunderstanding something, but it looks like either the
problem is not present on SPARC, or the comment is wrong: patch 4910101
is for x86 platforms only.

In any case this looks wrong and needs to be fixed.
