I'm trying to figure out where the PIE check can go.  Moving it to 
Makefile.housekeeping (or to arch/x86/Makefile) breaks the 
bin-x86_64-efi build due to some unknown relocation types.

You can test any proposed patch: it needs to be able to pass

   make everything

which will build a selection of 32-bit and 64-bit x86 targets.
