Yes - the use of git submodules guarantees that everyone building from
version-controlled sources has the same version of gnulib, by virtue of
the fact that the submodule for gnulib records that version.  Both
coreutils and m4 use this approach, and it has worked out rather nicely.
Findutils uses a similar approach where it records the latest version of
gnulib tested, but not as a git submodule.

Actually, for m4, I'm now at the point where I perform more gnulib imports
than I do configure.ac changes.

For m4, the bootstrap script takes care of running autopoint prior to
gnulib-tool --import, then runs autoreconf with AUTOPOINT=true.
