add new gen/ directory for generated sources
Allow modules to generate source into $OUT/gen, which will then
be copied into $OUT/obj and $OUT/obj_$(TARGET_2ND_ARCH) as
necessary. This allows a single build rule invocation that includes
generated source to build for the first and second architectures.
Modules will need to change calls to local-intermediates-dir into
local-generated-sources-dir.
