[OpenBIOS] need help building sparc32 crosstool

[Robert Reif]

It's been a few years since I did any qemu and openbios hacking
and I want to give it another try.  I'm using ubuntu 10.10 on a PC
but my last development work was on redhat 9 so things have changed.

I need to start from scratch so could I get some advice on what
compiler and glibc version everyone is using.  I remember getting
a working crosstool took some effort but I don't remember what I did.

I assume people are still using crosstool-0.43? It that still true?
What about crosstool-ng?  Something else?

Thanks in advance,

Bob.
