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.

4 Subject: [PATCH 14/15] LT pthread_atfork: unhide
6 Trying to compile perl with uClibc new linuxthreads on arm.
7 I run into the problem that pthread_atfork is not available.
8 The problem was that it was synced with the glibc version, which has
9 compat ifdefs we do not need in uClibc. The inital checked in version
10 is right and works. So either revert the commit 2 years ago
11 or patch it with the patch attached I made for openembedded.
