I can get this to work if I replace your:

>      EXPAND += favorites.h@
>      INC += favorites.h

with this:

>      EXPAND_VARS += FAVCOLOR=red

There are some special rules for include files listed in INC which
assume that they will get created in the O.Common build directory
instead of O.$(T_A) if they can't be found in the regular source
directories. Setting INSTALL_INC directly prevents those rules from
being applied.

HTH,
