- - For reasons I don't understand, xentools48 is forcing a dependency on

- I attempted to remove the dependency on pkgsrc GCC on NetBSD

Ok, I've got the results of an attempted building using the
stock gcc on NetBSD 7.1/amd64 (XEN3_DOM0).

It looks like the builtin gcc is having a problem finding a
needed include within the include tree.  The excerpted error
(the first of many) is:

The full build log is at ftp.cirr.com:/pub/eric/xentools48-standard-gcc.out

Hopefully this helps someone sort out the issues with the build.
I'd do it but I don't have time to chase it down right now.
