Correct, I don't want to Make src/ twice.  However, there is a
dependency which I think is lost in the removal your suggest.

Before build-improvements was created, Axiom used to build a locally
patched version of GCL which needed objects from src/lib (sockio-c.o
and all that).  So, the very first thing the makefile did (after
building noweb) was to Make src/lib (and not any other sibling
directory). After that, GCL is made, then src is walked starting with
boot/, interp/ and so one.  But you src/ in general depends on
lsp/, which itself depends on src/lib.  

Now that we don't need to build a patched version of GCL, we do
this:
  (1) build noweb if necessary
  (2) build GCL if necessaary -- as if we build on its own; however
         install in $(axiom_builddir)
  (3) build a Lisp image that contains objects from src/lib
      (a) so, we must have built src/lib before building the Lips image.
