Using libnbcompat is more than simply just linking in the library.
You have to also convert the sources to use the <nbcompat.h> header.
There's no good way to do this automatically, yet, although I have
some ideas that I plan on implementing after the next pkgsrc branch
is cut.

I will consider adding this in the future, but for now, libnbcompat's
purpose is primarily to aid in bootstrapping pkgsrc, which means it
only has just enough code to help build the bootstrap utilities on
various non-NetBSD platforms.
