This can cause surprising errors if the build tools is built against headers that don't match the host system. It is also required in order to allow building on non-FreeBSD systems where the headers in /usr/include/sys are usually completely incompatible with those in the source tree. I added an error to Makefile.boot if this is done and found this was only the case in libnv. With this error in the Makefile ABI breakages such as r336019 should no longer be possible.

$FreeBSD$ This directory tree contains tools used for the maintenance and testing of FreeBSD. There is no toplevel Makefile structure since these tools are not meant to be built as part of the standard system, though there may be individual Makefiles in some of the subdirs. Please read the README files in the subdirs for further information.
