Mike Kinghan <mikek@symbian.org> [Thu, 25 Nov 2010 14:08:02 +0000] rev 133
Provide an option for the base/rom extension that causes the toolchain id (ARMCC or GCCE) to be defined for
the C preprocessor phase of rombuild, enabling rom files to be conditionally included or excluded depending
on whether the toolchain can build them. This mimics the same change for Beagleboard.
