gcc 3.0.1 does not work on Solaris 8/sparc

[Hubert Feyrer <hubert dot feyrer at informatik dot fh-regensburg dot de>]

I have tried building latest gcc (3.0.1, and also -current CVS checkout),
with little success. The C compiler compiles, but libstdc++ blows up.
The patch attached below works around the (known broken!) problem of "ln
-s -f" not working in Solaris by doing an explicit 'rm' first.

Before I drop gcc >3.0 into the dustbin now, let me tell you I'm very
disappointed by the state this is in. Having used (and installed) gcc for
many years (>8) on Sun systems now, seeing the state of gcc 3.0.1 makes me
wonder where the quality of all this went to. GCC used to work/compile out
of the box on a Solaris machine. Seems that's no longer the case.
