Ah, I've made Parrot build again on Linux PPC (and make testj only has
the expected t/library/streams.t failure present with make test too).
The attached file works as the eventual src/platform_asm.s file, at
least on my architecture. I'm not sure how to plug it in to the
generated fileset cleanly, but that's a lot easier than trying to debug
assembly code on a platform you don't have.
Leo, what do you suggest to connect the dots here?
