Snart, please update your git clone.

With the just pushed 80c449e commit, the path of the awk tool found by configure
is diffused to po Makefiles.

With that patch applied, I changed configure.ac to search for mawk instead of
gawk. I now have an error when running 'make update-po' in a po subdir, because
of incompatibility with mawk.

Can you please confirm ?
