[PATCH] kvm-userspace: kvmppc: fix building userspace for powerpc

[ehrhardt@linux.vnet.ibm.com]

From: Christian Ehrhardt <ehrhardt@linux.vnet.ibm.com>

Commit 2d5737d8 added the requirement for an $arch/Makefile.pre in the
kernel subdirectory. This patch adds a stub for powerpc.
Additionally now a file kernel/$arch/hack-module.awk is needed and a simple
version for ppc is added for that one too.
In the root Makefile ia64 patch 030253bf added ia64 with a comma which should
break both architectures because filter works without. The patch removes that
comma.
The commit 76ff90aa fixed the dependency to DEPLIBS, but the definition of the
libfdt dependency lacks the right path (../libfdt/).
