Define SECTION=* and SECTION_IS_* when compiling
The linker scripts are passed through the preprocessor so that
they can distinguish between RO and RW images. This change makes
the same macros available when compiling, so that code can
contain directives like
#ifdef SECTION_IS_RO
or
#define FW_SIZE_(section) CONFIG_##section##_SIZE
#define FW_SIZE(section) FW_SIZE_(section)
int size = FW_SIZE(SECTION);
BUG=none
BRANCH=none
TEST=make buildall
Nothing uses this yet, so there's no change to the images.
