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 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch
2 Set the default behavior on alpha to use -mieee since the large majority of
3 time we want this (bad/weird things can happen with packages built without
6 To satisfy those people who may not want -mieee forced on them all the time,
7 we also provide -mno-ieee.
