A problem similar to this was reported to me recently for building
some .oct files on Cygwin.  The quick fix was to add the other
libraries to the link command.

Would there be any harm in havingg INCLUDE_LINK_DEPS == true on all
systems?  I've just checked in some changes to make that happen, so I
suppose we will see.  It seems to work fine on Debian, and I don't
know why it would not on other systems as well.

Also, I added FLIBS to the definition of LINK_DEPS in mkoctfile.  Is
there any case where that could cause a problem?  We already link to
libcruft, which depends on FLIBS, so I don't see how it could.
