The multiboot and PVH entry points are not used in the PE binary, hence
discard them in the linker script when doing a PE build.
That removes some relocations that otherwise appear due to the entry point
code in head.S not being position independent.
No functional change intended.

We could also place the entry points in it's own isolated section and skip
such section for relocations generation in mkreloc, but it seems best to
just remove the code if it's unused.
