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
[DEBUG] ==> Executing: 'make' '-j3' '-s' 'check'
[ALL ] Making check in .
[ALL ] config.status: creating include/cloog/cloog-config.h

it to the linker command line

[ERROR] make[1]: *** [check-recursive] Error 1
See:
https://wiki.ubuntu.com/NattyNarwhal/ToolchainTransition
This patch fixes these errors by placing '-lm' at the right place on the command
line as libppl requires libm when linking cloog.
