The branch was intended as a playground for several things I wanted to 
test, which is why I changed it from just x86_64 to jh. So it's not just 
about other architectures. There are some other key changes I've made 
there that haven't found their way to trunk yet. Like the 
--disable-shared for GCC pass 1, the move of the bootstrap to pass 2, 
the textual changes, the upcoming 'choose a bootloader' type section.

I'm happy to continue using it as such and continuing to work there, but 
the idea of creating a branch for each arch before merging to trunk has 
some merit, too.
