rule to accomodate gcc4, which no longer support SGI as.

- eliminate ambiguities between GNU-ish and SysV-ish make flavors;
- switch [back] to -e;
- fold/unify rules;

This is follow-up to the patch introducing common BUILDENV. Idea is
to collect as much parameters in $(TOP) as possible and "strip" lower
Makefiles for most variables [and thus makes them more readable].

I noticed "make report" didn't show the cc version on most of
my System V platforms. This patch corrects this.

update target, place the dependency on depend last, so all necessary files
are generated *before* the dependencies are figured out.

1107.  He says:

This is a followup to the NetWare patch that was applied to beta3.  It
does the following:

- Fixes a problem in the CLib build with undefined symbols.

- Adds the ability to use BSD sockets as the default for the OpenSSL
  socket BIO.  NetWare supports 2 flavors of sockets and our Apache
  developers need BSD sockets as a configurable option when building
  OpenSSL.  This adds that for them.

- Updates to the INSTALL.NW file to explain new options.

I have tried very hard to make sure all the changes are in NetWare
specific files or guarded carefully to make sure they only impact
NetWare builds.  I have tested the Windows build to make sure it does
not break that since we have made changes to mk1mf.pl.

We are still working the gcc cross compile for NetWare issue and hope
to have a patch for that before beta 6 is released.
