I'm afraid this sends us back to the drawing board.  We can't simply use
"AR = gcc ..." to build shared libraries because they need to link to
each other.

What were the reasons for building this way again?  I can see that it's
helpful to build the static libraries without -fPIC, but one can do this
by building .lo objects with -fPIC and making the shared libs with
those, like libtool does.

I'm afraid I'm going to have to revert much of the recent work to -4 and
try to fix its problems a different way...
