Please give-back libowfat on x32

[Christian Seiler <christian@iwakd.de>]

Dear x32 porters,

please give-back libowfat on x32. I'm the maintainer of
dietlibc and have recently fixed a couple of bugs in dietlibc
that caused libowfat to FTBFS on x32 (see #850276), and
libowfat should now build on that architecture.

gb libowfat_0.30-2 . x32

Thanks,
Christian
