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: ../4.3.2/110-trampolinewarn.patch
3 -= BEGIN original header =-
4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch
5 This trivial patch causes gcc to emit a warning whenever
6 it generates a trampoline. These are otherwise hard to
7 locate. It is rigged to default ON - to have it default
8 to OFF remove the text 'Init(1)' from the common.opt
9 patch, leaving just 'Common Var(warn_trampolines)'.
