Actually, there is a reason to do this.  We take all of our PIC objects 
and put them into a libfooS.a as well as libfoo.so.  This is useful if 
you want to link libs together or if you have specialized tools.  For 
example, our IDE has a dietician which will calculate all the .so 
dependencies of a project and create small, custom shared libs only 
containing the needed code.
