Remove the time_t and suseconds_t TYPEDEFs from alltypes.h.in. They
are no longer allowed to vary per-arch. Then make sure you rebuild
*everything* (libc, the test suite, any other code you're linking
against musl and trying to use). I'm pretty sure you have a mix of
files that have been build with different things you've tried and that
is the source of your problems.

These files are only used on archs that had an old ABI with 32-bit
time_t, which I asked about before and you seemed to say you don't
have. If you *do* actually have an existing ecosystem of stuff that
possibly needs to keep working, we need to figure out what that is and
whether it's even possible to support (it might not be if it's a
mess/mix of different things you've tried). If not then these files
will not even be built and are not needed.
