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:

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

 The m68k mcpu processor does not like unaligned access

 Disable at least mcpu32, m68010 and m68020. These processors certainly

 do not like unaligned accesses.
