[PATCH] configure.ac: Resolve GIT_SHA even if repository is a submodule

[PATCH] configure.ac: Resolve GIT_SHA even if repository is a submodule

[Niklas Söderlund]

If the v4l-utils repository is a git submodule the $(top_srcdir)/.git is
a file and not a directory. Update the shell check to allow the test to
pass in both cases.

Isn't the same change needed here and in GIT_COMMIT_DATE as well?
