Yipes.  I suppose it's far too late to suggest that that convention is
guaranteed to create porting problems?

I suspect that some such hackery will be necessary on almost every
platform.  Maybe you should put LDFLAGS_ODBC into the template files
instead of the port makefiles?  I've never been real clear on why
we have both sets of mechanism...

Anyway, I'd suggest making all of the LDFLAGS_SL assignments in
Makefile.shlib be += rather than :=, and then the Makefile for the
ODBC driver can add on the LDFLAGS_ODBC from wherever we decide to
get them.  Are there any other hacks besides setting more flags that
we are likely to need?
