It will. You can even add CPU targets. I generated an entire lazarus for Mac
OS X/PowerPC on Windows.

But there are caveats:
- you must have suitable crossbinutils on Windows.
     Some are available on ftp in the /pub/fpc/contrib and 
     /pub/fpc/contrib/cross directory
- non windows systems typically need any needed libraries on the compiling
   system. Simple programs for Linux and FreeBSD excluded.
   
The buildfaq contains a lot of background info on this.

Not units, but on e.g. BeOS and OS X, it might use libraries. (like libc).
The rtl of these interfaces libc.
