OK, than I didn't look close enough.

It's all x86 cross compilers (they will build for mipsel, on x86):


# pwd
/opt/crosstool/mipsel-unknown-linux-uclibc/gcc-3.3.3-uClibc-0.9.23/mipsel-unknown-linux-uclibc/bin
# file gcc
gcc: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for 
GNU/Linux 2.2.5, dynamically linked (uses shared libs), for GNU/Linux 
2.2.5, not stripped

# pwd
/opt/crosstool/mipsel-unknown-linux-uclibc/gcc-3.3.3-uClibc-0.9.23/bin
# file mipsel-unknown-linux-uclibc-gcc
mipsel-unknown-linux-uclibc-gcc: ELF 32-bit LSB executable, Intel 80386, 
version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared 
libs), for GNU/Linux 2.2.5, not stripped


So I guess I need to spend some more time on it, if I don't figure out, 
I'll keep on asking :)
