Getting GCC to cross-compile for MIPS

[Bret Indrelee <breti@bit3.com>]

I am having trouble getting GCC to cross-compile for MIPS.

I have native versions of the following GNU tools installed:
	autoconf-2.12
	m4-1.4
	gcc-2.8.1
	make-3.77
	patch-2.5
	binutils-2.9.1

I then tried to follow the FAQ instructions for crossgcc, installing the
patch and creating binutils before attempting to install gcc.

I have the header files for the environment that I'm going to use, so
when configuring gcc I gave it the --with-includes=$(DIR) directive.

cc      gcc
host    sparc-sun-solaris2
prefix  /nfs-home/breti/cross-mips
shell   /bin/csh
target  mips64-elf

It fails in the 'make all' for gcc.
$ ../gcc-2.8.1/configure --target=$target --host=$host --prefix=$prefix
--with-includes=/nfs-home/breti/nec-pmon/include -v
$ make all

... lots of stuff works ...

There is a ../gcc-2.8.1/mips-tfile.c, but it appears to only be intended
for native mips compilation. I'm not familiar enough with MIPS to figure
out what it is supposed to be, it looks to be related to the elf file
format.

Any suggestions?
