>Description:
	I tried to build the toolchain on a FreeBSD host (I know, it is not officially supported).
	
	First, I had to clear BSDSRCDIR and BSDOBJDIR since they were sticked to /usr/src and /usr/obj, as shown by
	"./build.sh .... params". Dunno if it matters.
	
	Second, I was looking in the output for references outside the source tree, for two reasons 1- not to nuke my FreeBSD src
	2-I sometimes ran into a NetBSD hosted build using installed includes rather than those from source tree. It *generally* is
	not a problem, but sometimes, I had to boostrap with a "make includes"
	
	And in fact, I found the build process using FreeBSD's includes, which obviously is incorrect.
	
>How-To-Repeat:

Here is the build environment :

(note that /etc/mk.conf does NOT exists, purposely.
