Oh, I just realized - we've had gcc (or maybe "as") bugs when the weak
symbol is in the same compilation unit as the caller, and some part of
the toolchain just ends up short-circuiting it (either gcc inlines it,
or maybe it was that as resolves it early). Making the "weak" part not
work, because it binds strongly.
It may be that we don't support those gcc versions any more, but I
thought I'd bring the issue up. It's safer to put the weak functions
in some other file if possible.
