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.

1 If gcc is configured to generate i686 code or better by default (like
2 when using the --with-arch=pentium3 configure option), then the __i686
3 macro will always be defined automatically and thus screw up the
4 compilation of some .S files.
