llvm: fix sparsec breakage on recent cygwin version

On recent version of cygwin, sparsec fails because, apparently,
 lcc is using the wrong triple. This is because:
1) sparse-llvm doesn't use an explicit triple for cygwin;
2) by default, llc use triple of the host machine at
   build-time as the the default for the target machine.
Why/how it was working with previous versions is unknown.

Fix this by using, on cygwin, the triple given by llvm-config.
