complibs/cloog: create missing m4 dir

Because we now patch configure.in and configure, the Makefile quicks
in a re-build rule as the source files are now more recent than the
bundled generated files, and that fails because the m4 directory
is missing, although on some systems where aclocal is not installed,
the re-build rule does nothing (except a warning).

Always create tht directory.

This means that the unknown character is no longer ignored, despite the
yann@56
    45
comment.  As a side effect a line starting with a line comment character
yann@56
    46
not followed by APP in NO_APP mode now triggers an error instead of just a
yann@56
    47
warning, breaking builds of glibc on m68k-linux.  Earlier in
yann@56
    48
read_a_source_file where #APP is handled there is another comment that
yann@56
    49
claims that unknown comments are ignored, when in fact they aren't (only
yann@56
    50
the initial line comment character is skipped).
yann@56
    51
yann@56
    52
Note that the presence of #APP will mess up the line counters, but
yann@56
    53
that appears to be difficult to fix.
