Indeed that's one option to build it, that's for example the solution
chosen to build slof using gcc-powerpc64-linux-gnu. So far nobody
complained it's buildable only on amd64, i386, ppc64el and x32.

The other alternative is to build a cross-compiler using binutils-source
and gcc-source (that requires that the none or elf os is supported for
this architecture). This has the advantage of ignoring all the flags
that debhelper tries to push that make a firmware to not build or break.
That's the solution chosen for example for openbios.
