To avoid programs that use compel to have some sacred knowledege
(the library name and the path to it), same way as pkg-config does,
but with added bonus of handling the uninstalled case (compel
is in our sources). In other words, to eliminate the lines like this:

COMPEL_LIBRARY	:= ../../../compel/libcompel.a

from the makefiles that use compel.

Now, I just realized I made a slight mistake -- if libcompel.so is 
installed into
the standard libdir path (what are the standard paths? how can we get 
those?),
the output of "compel libs" should be -lcompel. I will send the 
follow-up patch.
