>Description:

'make USE_NEW_TOOLCHAIN=no' doesn't work because the code used by
bsd.own.mk uses .undef and you can't .undef a variable set on the
command line. Since the command line is where most people are likely
to put ad-hoc variables, this makes a quick test of
USE_NEW_TOOLCHAIN=no more difficult than it needs to be. 

I have labelled the priority medium rather than low because I went
bugfuck trying to work out why 'make USE_NEW_TOOLCHAIN=no' didn't
work.

>How-To-Repeat:

make -dcv USE_NEW_TOOLCHAIN=no

Watch the .undef get executed, and then watch CPPFLAG_ISYSTEM get set
to -isystem.

>Fix:

It would be nice to make bsd.own.mk abort make if the .undef of
USE_NEW_TOOLCHAIN doesn't work. I don't know how to make abort.
