Within the OE build environment, we supply the correct fpu settings. These only need to be spelt out for the on-target gcc. Doing this means the checksums for the core compiler don't depend on the fpu settings. We exclude the compiler tunes for similar reasons, it doesn't need to influence the compiler build.
