powerpc: "make install" broken

["Alex Riesen" <raa.lkml@gmail.com>]

I don't know if ever worked before, just tried today on v2.6.17.
Maybe it works, but then it is very different to i386
where it is plain "make install".

I copied the implementation attached from i386 (modified a bit), which
fixed it for me. Maybe the patch will motivate someone to fix it properly...
