[PULL 03/20] configure: simplify assignment to GIT_SUBMODULES

[Paolo Bonzini]

Do not guard each assignment with a check for --with-git-submodules=ignore.
To avoid a confusing "GIT" line from the Makefile, guard the 
git-submodule-update
recipe so that it is empty when --with-git-submodules=ignore.
