[Buildroot] [PATCH 3 of 3] oprofile 0.9.8: fix compilation on powerpc

[Reuben Dowle]

This series of patches fixes my build error I got when updating to latest buildroot sources on Friday. Fixing this was going to be my first task this Monday. Thanks!

I will check everything is working on my target later today. One possible minor change below:

I think this dependency is only needed for powerpc. So something like:

OPROFILE_DEPENDENCIES = popt binutils
ifeq ($(BR2_powerpc),y)
OPROFILE_DEPENDENCIES += libpfm4
Endif

Might be better?
