GCC2 removed, vax port downgraded to static-only for now.

hi folks.


i have removed GCC2 sources from our tree and switched the
vax port to
GCC3.  unfortunately the shared library support is missing
and so the
vax no longer supports shlibs in -current.  the support for
them is
planned to return with the switch to GCC4 on vax.  i do not
know when
that will happen.

it is possible i have damaged the tree in other ways, please
send-pr
if you notice new build problems.
