Hm, interesting, now OpenBSD build is completely broken (it already
failed all H.264 tests so it's not that much of a change in some way).
I think M?ns mentioned it already to me but I don't remember the
details, anyone knowns what's going on? Seems configure things ebx is
available but at least for these functions it is not...
I remember one issue with the Haiku compiler, namely that in asm
construct using a ebx clobber would compile but one using a "b"
constraint wouldn't.
    check_asm ebx_available '"":::"%ebx"'
maybe be changed to
    check_asm ebx_available '"":"=b"(x)::'
