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.

3 reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,
4 MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,
5 for e500v2 DPFP support) and will generate appropriate dual-precision
6 floating point instructions by default.
8 Note: If building a Linux kernel with this toolchain, you will want to make
9 sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions
10 from getting into the kernel (which is currently unsupported). At this time,
11 the kernel build system properly passes those two options, but older kernels
12 were only passing -mno-spe by default."
