Crosstool-ng arm-config breaks on x86 gentoo.

[XVilka Haos of System <xvilka at gmail dot com>]

Good day!

I'm always successfully use crosstool-ng for my own arm hardware and
successfully built toolchain on x86 linux.
But after i'm changed my distro from Debian to Gentoo - i'm found
strange problem:

building of toolchain breaks, because compiler dont have -mlittle-endian option.
This is easy changed by recompiling gcc, but i tnink that such
dependency dont important and must be killed in your GREAT tool :)

Here the logs and some info of compilers:
