[PATCH] powerpc: Fix build dependencies for epapr.c which needs libfdt.h

[Matthew McClintock]

Currently, the build can (very rarely) fail to build because libfdt.h has
not been created or is in the process of being copied.

I think this fixes this build error. Please comment as it's really hard to
reproduce this build error. I've seen this happen a few times now on our
automated build server.
