I *might* volunteer to fix x86 target toolchain because I know for sure
that I need it in the future
because Im currently making my own uClibc based, buildroot assisted,
distro and that's why
having a native uClibc toolchain is crucial for me.

But not before I have keeped my soon to be starting, 3 weeks vacation.

So please Thomas, don't remove it just yet while im away :)
