Build failure on kfreebsd: Don't know if OSUnknown is elf

Hi,

the 7.4.1 release candidate failed to build on the two Debian ports based on the freebsd kernel; previous versions built fine. It would be great if arm support would not be dropped, if it can be helped:

To the best of my knowledge, kfreebsd does use the ELF format.

Thanks, Joachim on behalf of the Debian Haskell Team
