[package] lsof: cross-build properly

I found that the lsof build was using the build host's ar and ranlib
instead of the target's. That's tolerable when the build host is
Linux/ELF. It's not so great when building on Mac OS X.

I also found that lsof was reporting that it was built with the native
compiler instead of the cross-compiler.
