Nice catch.  It looks like your mkdir was not the first in the path,
so the existing attempt to cleanup did not fire.  Fixed thusly

        Unconditionally check for junk ./--version after mkdir search loop.
        * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Always check for
        presence of ./--version.  Reported by Eric Blake.
