Comment (by jeremyhu@…):

 I think that this is a bad idea.  I would prefer to remove xnu-headers and
 libc-headers.  Ports should not depend on them and should use the ones
 from the host.

 libunwind-headers should be moved back to installing into
 ${prefix}/include, and we should understand why that was causing failure
 in other ports and fix *those* ports.

 libmacho-headers similarly is fine being in ${prefix}/include.  Similar to
 libunwind-headers, they are the headers for the MacPorts-provided libmacho
 port but can also be used as declarations for the base OS-provided
 implementation in libSystem.  If they cause problems in other ports, those
 other ports should be fixed.
