    Merge branch 'am-prog-mkdir-p-remove' into ng/master

    Since we had to restate AM_PROG_MKDIR_P in master before the 1.13
    release, we don't merge master directly in ng/master, to avoid spurious
    merge conflicts (since AM_PROG_MKDIR_P should remain obsolete and
    removed in Automake-NG).

    We have thus create a temporary branch 'am-prog-mkdir-p-remove', based
    off of master, which reverts the commit 'v1.12.4-158-gdf23daf', which
    reinstated AM_PROG_MKDIR_P, and are merging that branch in 'ng/master'.

    Once 1.13 is out and master becomes the starting point of Automake 1.14,
    we'll merge the 'am-prog-mkdir-p-remove' branch back into master as well,
    since we plan to remove AM_PROG_MKDIR_P once and for all in Automake 1.14.

    * am-prog-mkdir-p-remove:
      AM_PROG_MKDIR_P: remove as obsolete, this time for good
      depcomp: avoid potential interferences from the environment
      depcomp: improve comments about the 'gcc' depmode
      compat: reinstate AM_PROG_MKDIR_P, for gettext
