No. There's a bunch of fixes that need to be applied to gcc and binutils
to get it to find the right libraries in place of the normal libc environment.

The buildroot environment is big!, but the toolchain is a lot smaller to
build. I've even just hacked up my toolchain to only build gcc and binutils.

So I suggest you start with the toolchain - it has all the stuff you need.
