It is basically working quite well.  Unfortunately there is a big
problem which becomes apparent when running the libstdc++ testsuite: the
m68k compiler only guarantees a maximum alignment of 2 bytes, but the
futex syscall requires 4 byte alignment.  So if your pthread mutex is
not aligned on a 4 byte boundary this will result in passing an
unaligned address to futex.  I haven't yet decided on what would be the
best way to fix that.
