aarch64-targeted cross-compiler definitely does not make any sense on aarch64 and armh (native or multilib compilers are available). Using 32-bit x86 as a development platform does not make any sense either. Same applies to mipsel. ppc64el and e2k might be powerful enough but these machines are way too rare/expensive.
