"Official" means "if I report a bug w/o a patch in this list, I don't
get a message which requests to change the tools". 

I think, Ralf is the "officier" who decides what the right toolchain is.
Now, last toolchain Ralf announced was 

- binutils

Binutils were buggy handling a cases involving empty object files.  I've
uploaded fixed binutils 2.8.1 cross-linker packages to oss.sgi.com; 
I'll
upload fixed binutils 2.9.5 binaries (mips64 only) later.  The
worarounds
for this bug have been removed from the CVS archive that is updating is
required for building a current 2.4 kernel.

I've uploaded new egcs 1.1.2 based crosscompiler to oss.sgi.com into
/pub/linux/mips/crossdev/.  The only change for version 1.1.2-4 affects
mips64-linux and mips64el-linux targets where asking for alignments
larger than 8 bytes was ignored with a warning message.  This did
possibly result in some performance penalty for mips64 kernels.

The faq does mention this toolchain still.

Ralf, are you going to announce new toolchain given the lastest kernel
can't be compiled with old one? Or shall we change back the sources?

Gleb.
