Drop copy step from the rts/

Recently I've used a different build system for building the
rts (Xcode).  And in doing so, I looked through the rts/
to figure out how to build the rts.

In general it's quite straight forward to just compile all the
c files with the proper flags.

However there is one rather awkward copy step that copies some
files for special handling for the rts way.

I'm wondering if the proposed solution in this diff is better
or worse than the current situation?

The idea is to keep the files, but use #includes to produce
identical files with just an additional define. It does however
produce empty objects for non threaded ways.
