    Yes, I understand that you have a circular dependency there, but fixing
    the ABI can only become harder with time, as more people start using
    the current kernel/toolchain combination.

    I had hoped that the way I set __ARCH_WANT_SYSCALL_* in the microblaze
    unistd.h would provide an easy way to migrate, because this still defines
    almost all traditional system calls (I haven't double-checked if some more
    are currently used on microblaze, but they would be easy to add).
    This means that as a first step, rebuilding the tool chain (as above) should
    be sufficient and not require source-level changes to libc. From that point,
    you can remove the remaining __ARCH_WANT_SYSCALL_* defintions one by one,
    and change the libc accordingly.

    I could also try building uclibc with the generic headers if I find the
    time. Which version do you use, just upstream or do you have a private
    libc tree with more changes?
