(My fault. imcc needs to be built with $(LINK), not $(LD). I'll send a
patch separately.)

Soon, parrot will use perl5's $Config{ld} and $Config{lddlflags} which are
variables designed for just this purpose of building shared libraries.

This is a bigger (but very real!) problem. Building a shared library is
not simply repackaging the existing objects. If we want to build a shared
library, we should re-compile the components with -fpic or equivalent. The
actual variable we need is perl5's $Config{cccdlflags}.

I'd like to hand this one off to someone who understands why we have to
build a shared library in the first place and what, eventually, we might
have to do with it. (For example, what's the plan for platforms that
can't do dynamic loading?)
