nobody says that you should mess with your debian toolchain.
but you should build a properly configured, musl-agnostic toolchain so
that the binaries you produce don't work by luck only.
(using a different prefix so everything is safely kept away from your
debian TC)
as a reference you can either look at the musl-cross project (you can
probably even compile that straight on ppc without changes)
or use the sabotage build scripts. see the musl wiki for links to these
projects.
even better, you could just get the sabotage powerpc rootfs, extract it
into a temporary directory and use the included native gcc 4.5.4 (it's
in /opt/gcc4 inside the rootfs).

150 MB
be sure to unpack inside a newly created temp dir.

no, we do not intend to support broken configurations that produce
broken code.
