dlopen cloog-isl library rather than link to it directly.  This prevents
cloog upgrades that change the soname from breaking the compiler.

http://pkgs.fedoraproject.org/cgit/gcc.git/tree/gcc5-isl-dl.patch


In FreeBSD dlopen is part of libc so we can't just hardcode -ldl.
We abuse the existing plugin check logic to pull out that info.
