Yes, this time I ran the testsuite natively, so I think a lot more of
the tests have run (and passed), consequently taking much longer (3.5
hours).  I guess the same tests would have failed again, so maybe
there's no use.

This run also includes the sigreturn patch below.

Thanks for the explanation.  I guess the DoSyscall function can then
be used instead of this assembler code?  Then there won't be yet
another ifdef here.
