${SCONS-OUT}, as in the clause above for ARM? Also, is the rm/mkdir not
necessary? If so why?

[robertm, 2012/05/04 20:52:44]

I think it would be good to factor the code into a new function and then have
something like

 rm -rf  "${INSTALL_ROOT}/tools-x86"
 mkdir "${INSTALL_ROOT}/tools-x86"
 build-arm-validator <args>
 build-mips-validort <args>

Ok, we will refactor it this way.
