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 This is a somewhat ordered TODO list:
5 - update versions for every tools...
7 - update and/or upgrade all samples
12 - update newlib (for enhanced bare metal)
13 - confirm existing implementation on targets other than AVR32
14 - try to make it generic, will help for uClibc++
18 - Cygwin target (needs newlib)
19 - so we can build toolchains that generate code for Windows/Cygwin
22 - so we can build toolchains that run natively under Windows/Cygwin
25 - so we can build toolchains that generate code for Windows/Win32
28 - so we can build toolchains that run natively under Windows/Win32
29 (without requiring Cygwin)
35 - check whether we can use newlib under uClinux (?)
