O, thanks, but i know alrady about gaisler's toolchain. Compiler works well
and generates nice sparcv8-softfloat binaries. Also i've compiled kernel
successfully. Snapgear linux (as a whole) is #$% imho. Works bad. The
question is - how to intergate nice compiler with emerge. I feel that it
should be easy, but still can't  catch this thing..
