I'll try to give this a test when I get a chance, we currently have a
e5500 target that we're building binaries for but with a e500mc
toolchain (using arch compatibility mode on the processor).  Will the
buildroot toolchain do multilib so that it's possible to build uboot
32/36bit and a kernel 64bit?  So far that's why we stuck with the
e500mc (just 32/36bit) keeping us using a single toolchain.
