Haven't tried it so I'm probably way off base, but could this maybe simply 
be done by making the code in question just be:

If those options are set for a ROM it will want to have been loaded in 
ROM. To build for RAM you have to disable CYGSEM_HAL_ROM_MONITOR and set 
CYG_HAL_STARTUP to RAM, not very surprisingly really! Only the latter is 
required in fact as CYGSEM_HAL_ROM_MONITOR should set itself accordingly.
