complibs/cloog: fix linking with libm

In Ubuntu 11.04 and 11.10, the default options for ld have changed.
--no-copy-dt-needed-entries and --as-needed are now enabled by default, which
causes errors like:

[EXTRA] Checking CLooG/ppl

[ALL ] Making check in .

[ERROR] make[1]: *** [check-recursive] Error 1

See:

This patch fixes these errors by placing '-lm' at the right place on the command
line as libppl requires libm when linking cloog.
