I myself defintely never published anything 2.7.2.x based. Anyway, I
urgently recommend switching over to egcs 1.0.x and while you're at it
binutils 2.8.1-2. Sorry, no binaries for these packages available, just
patches against the vanilla FSF version. Go and download
/pub/linux/mips/src/binutils/binutils-2.8.1-2.diff.gz
/pub/linux/mips/src/egcs/egcs-1.0.3a.diff.gz
The whole procedure of building a crosscompiler is described on
www.linux.sgi.com.
I'll upload newer rpms whenever I find the time to do so.

Pilot error. You tried to compile the i386 code with the MIPS compiler and
wonder why the pyrotechnics are flying. General answer: pass ARCH=mips to
the make calls or modify the ARCH variable in the main Makefile to the value
mips or any other architecture you're building for. MIPS specific answer:
the messages above show that you're trying to build vanilla 2.2.10 which
doesn't have all the MIPS code. Fix: get a snapshot of the sources from
ftp.linux.sgi.com in /pub/linux/mips/test/ or checkout the linux_2_2 branch
via anonymous CVS. Details are described in the FAQ on www.linux.sgi.com.
Or just download a kernel binary ...
