Implement Guile linking for C builds

In order to write Guile code against C, I need to distiguish between libs and
bins, so I did that, then I got the flags that gcc needs from `guile-config` and
put them in the args for any C lib build. I tested this with Bessel.c and
Bessel.scm (not in this patch, because I don't really want that code in my
tree, I'll come up with another way to test it later).
