commit 9d84a81fe97400d669b5056ddcab9c59458d63e7
Author: Joseph Myers <joseph@codesourcery.com>

    Make accept4 for MIPS o32 avoid socketcall.
    
    sysdeps/unix/sysv/linux/internal_accept4.S expects socket.S to be
    present if __NR_socketcall is defined (which it is on MIPS o32, even
    though there are separate syscalls as well) and __NR_accept4 isn't.
    MIPS does not have socket.S, since it uses separate syscalls, but
    though the accept4 syscall should be added soon present kernel headers
    do not have it.  This patch creates a dummy internal_accept4.S for
    MIPS o32, and an accept4.c wrapper that undefines __NR_socketcall so
    that the main accept4.c falls back to the ENOSYS implementation if
    __NR_accept4 isn't defined; it doesn't seem worthwhile to have a
    special socketcall-based assembly implementation just for o32 on a few
    kernels in the range between accept4 being available via socketcall
    and the accept4 syscall being available.
