The reason for that succesfull build seems to be building from
a git clone. At least has the git submodule repository
  git://git.code.sf.net/p/gnu-efi/code
to be present.

That in other words:
   When not build from git I can reproduce the reported build error.



Place where it breaks is in efi/build-gnu-efi.sh at:

(
        cd ../..
        git submodule update --init
)

There are no checks on being in a "git checkout".

This patch makes the problem more visible:
