Subject: compiler building blocks: common definitions.
+ cbb-common.h: this target-agnostic header must always be included
when building cbb-gcc, but should have no effect on the code that
is generated by the resulting toolchain.
signed-off by Z. Gilboa; see copying.midipix (9cd0746c) for additional information.
