I don't know about ubuntu specifically, but in general there are two 
things you can do.

If you run gcc with the -pipe option, then it will try to run its 
subprocesses in parallel connected by pipes. Otherwise it'll run them 
one at a time using temporary files. This only helps compilation, not 
linking.

If you run make with its -j option, then make will build multiple 
targets in parallel when it can. For example, if make needs to recompile 
several files, then "make -j 3" would run three copies of the compiler 
at a time.
