mod_dav build fails on NetWare with unavailable exports

[NormW]

Looking at mod_dav exporting symbols not in use for NetWare, I've 
(shamelessly) borrowed the same pre-process method used for httpd.imp, 
which results in the following diff:

I can't call it my idea, but if anyone knows of a better way around 
this, would love to see it applied.
