Hello!

I'm new in embedded Gentoo, but i have some experience in embedded
linux. And now I'm want study embedded Gentoo!


At first I'm trying to build cross toolchain with crossdev.
Current architecture is not matter. I'm trying build for
mipsel-unknown-linux-gnu, arm-unknown-linux-gnu,
powerpc-unknown-linux-gnu, powerpc-405ep-linux-gnu and some other, with
different versions of binutils, gcc, libc... (according to google)
And, if other errors was resolved, I get "incompatible libgcc.a when
searching for -lgcc". It's most common error for me.

Any ideas are welcome!

P.P.S. Sorry for my English.
