Actually it does not yet really work the way I want ;-)
What I would like to obtain is that compiling with 'bjam 
<parallelism>=fake' and 'bjam <parallelism>=mpi' use the same object 
file (foo.o) but generate a different library. Because only the 
(dynamic) library depends on one or the other library. But the object 
file is totally identical so I would like to prevent to compile it twice.

So I tried to make the feature 'incidental' wich results in only one 
object file but also the library is created once ;-(

Sorry for being a pain in the neck, especially with my <parallelism> 
feature ;-(
