Problems building Windows hosted powerpc/arm/mips-elf toolchain using Linux as build machine

["Øyvind Harboe" <oyvind dot harboe at zylin dot com>]

I'm trying to build a powerpc/arm/mips-elf toolchain hosted on Windows using
Linux as the build machine but I'm running into the following error:

What I did:

- built toolchain hosted on Linux, generating mips-elf target code. Added it
to the path.
- ran script below
- gcc 4.3.2, gmp 4.3.2, mpfr 2.3.1, newlib CVS HEAD(>16.0), binutils 2.18
- I messed around with trying to add the right include files without too much
luck. The problem is that I don't really know what's wrong...
- tried GCC CVS HEAD
- tried some other targets without luck, same result. (arm-elf, powerpc-eabi).
- Once I have this working for Windows, I'll be able to build Cygwin hosted
toolchains in the same fashion.
