Final sanity pass: xdev

[M. Warner Losh]

OK.  I've had this reviewed before, and have been using variations of
this patch since 6.1.  However, since it has been a while, I thought
I'd see if there were any objections before I committed this patch.

It installs all the FreeBSD cross build tools as
$(ARCH)-freebsd-$TOOL, which is what autoconf looks for.  This may
help cross building ports, ultimately, but it is also nice for cross
compiling kernels (other changes to follow for that).

To build, just say 'sudo make xdev XDEV=mips XDEV_ARCH=mips' and away
you go.  Note: sudo is required, since we have to install the
compilers before building the libraries for the xbuild environment.
Each tool chain takes up about 75-100M of space.

Last call for Comments on this patch...

Warner

P.S.  See you at AsiaBSDCon '09, right? :)
