Didn't work. I wasn't thinking hard enough.

For OS X, three builds are attempted for three architectures.  That cannot
work with a single configure.

Maybe we need to throw our arms up in the air and just import the sources
files from pkg/src/ncl/ncl into pkg/src/ and treat them as part of the
package.

Or, go the other way, and require the user to have a suitable libncl
somewhere.
