[glibc PATCH] fcntl: put F_OFD_* constants under #ifdef __USE_FILE_OFFSET64

One way to fix that would be to add fcntl32() that does the flock <->
flock64 translation for F_OFD_XXX and calls the generall fcntl()
implementation. Then select between fcntl() and fctnt32() on 32bit
architectures based on _FILE_OFFSET_BITS in the preprocessor in the
fcntl header. That way we wouldn't have to touch the kernel at all.
