[Clfs-support] Problem compiling glibc

[Per Andreas Gulbrandsen]

Hi.

I'm kind of a n00b, so please bear with me.

I'm following the clfs guide for cross compiling a linux system for
mips (CLFS_TARGET="mipsel-unknown-linux-gnu"). SVN Version
SVN-20090107-MIPS. My host system is openSuse 11
(CLFS_HOST="x86_64-cross-linux-gnu"). I've checked host requirements
and I have all tools specified there.

I get stuck in 5.11, Constructing Cross-Compile Tools - glibc. When I
try to make I get the following error:
mipsel-unknown-linux-gnu-gcc -mabi=32

I've looked at asm/byteorder.h, but I can't figure out what to do. I
can't understand how I'm suppose to "fix" it. I've tried different
stuff, i.e. undefing __MIPSEB__ and/or __BIG_ENDIAN if __MIPSEB__ is
defined. But I still get the same error.
However, If I undef __BIG_ENDIAN in /tools/include/linux/byteorder.h
just before the check that triggers the error it compiles. But this
doesn't seem like a very good solution. Seems like I should get rid of
the initial definition of __BIG_ENDIAN (alt. __MIPSEB). Can anyone
please advice? I'd like to get this right, and not just hack my way
through it.
