[Boost-build] passing INSTALL_ROOT into bjam

If I have an install rule like this in my Jamfile:

install dist: /common/foobar//foobar :
<location>$(INSTALL_ROOT)/usr/local/lib ;

(and a default value for INSTALL_ROOT is defined in my Jamroot),

how do I overide the value of INSTALL_ROOT on the command line?

I tried -s option for bjam but didn't seem to have the desired effect.

I'm calling bjam from a higher level build script that needs to set
INSTALL_ROOT.
