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.

Without this patch, the sec script that processed initfini.s removes a
yann@1625
     8
part of inlined call_gmon_start, causing undefined label errors.

This patch solves the problem by forcing gcc not to inline
yann@1625
    11
call_gmon_start with __attribute__ ((noinline)).
