Once created there's no point re-creating them on every incremental
make. This in particular prevents them from becoming root-owned during
e.g. "sudo make install-xen", but it also allows (during development)
to replace them there (instead of in common/efi/) by actual files with
perhaps slightly changed contents.

Note that the root-owned issue also exists for the various .*.d2 files.
