nocopy option

[dmaclach@…]

When attempting to build up libc_debug there is a point where you need dtrace to generate up a header file for you. Since dtrace roots may be a long time coming due to their dependency on Foundation, I found it easier to run darwinbuild libc_debug up to the point it errored, call dtrace myself, and then restart darwinbuild. Problem was that it kept copying the old sources over my header. I added the nocopy so I could do the following:

darwinbuild libc_debug ... run into error... dtrace foo bar darwinbuild -nocopy libc_debug

and the world was good.

Gives darwinbuild the nocopy option to avoid overwriting your sources
