    Work around bug in mips+mipsel libc
    
    Forwarded: no
    Patch-Name: mips_dev_t.diff
    
    On mips and mipsel, the st_dev and st_rdev members of struct stat do not
    have type dev_t. This breaks POSIX compatibility, but is difficult to fix
    (cf. https://sourceware.org/bugzilla/show_bug.cgi?id=17786).
    
    To work around the issue, we change the definition of struct stat that
    is used by Cython when we are compiling under mips. Note that this
    requires the Cython compilation to run under mips, and that the
    resulting C file will be mips specific (without the patch, the
    generated C file is suitable for any architecture).
    
    Upstream is not interested in this change for obvious reasons.
