This patch adds support for feature fixups in modules. This involves
adding support for R_PPC64_REL64 relocs to the 64 bits module loader.
It also modifies modpost.c to ignore the powerpc fixup sections (or it
would warn when used in .init.text).

Normally, ppc64 module .ko files contain a table-of-contents (.toc)
section, but if the module doesn't reference any static or external
data or external procedures, it is possible for gcc/binutils to
generate a .ko that doesn't have a .toc. Currently the module
loader refuses to load such a module, since it needs the address
of the .toc section to use in relocations.
This patch fixes the problem by using the address of the .stubs
section instead, which is an acceptable substitute in this situation.

Also deletes files in arch/ppc64 that are no longer used now that
we don't compile with ARCH=ppc64 any more.
