When bootstrapping a GCC cross compiler targeting powerpc mac os using
https://github.com/tpoechtrager/osxcross/blob/ppc-test/README.PPC-GCC-5.5.0-SDK-10.5.md,
since version 13.2 at least, GCC fails the process with an internal compiler
error in rs6000_emit_prologue.
The error seems to be triggered by the call to __builtin_eh_return.
