CRDA and cross-compilation

Who currently owns CRDA?

I started to stare at cross-compiling issues, but realized that we need
two versions of reglib.o and print-regdom.o...

One to link with regdumpdb (compiled with HOSTCC) and one to link with
everything else (compiled with TARGET_CC)...

No easy way to do this without a lot of changes.

Here's what I have so far.
