make: don't use --whole-archive for loadable_module
make: don't use --whole-archive for loadable_module

r918 removed a hack and fixed it by introducing whole-archive.
Unfortunately, our loadable module link lines include lots of stuff
that doesn't belong in the loadable module.  Work around that so
that we're not stuck on an old version of gyp; hopefully with more
investigation we can trim these link lines as well.
