make: add generation of sorted symbol mapsstabilize-7059.B
Sorted symbol maps are useful when one wants to look up an address to
associate it with a function or a variable, or to estimate how much
room certain components of the image take.
This patch adds a rule and creates a dependency to make sure that
sorted maps (assigned extension .smap) are generated during builds.
BRANCH=none
BUG=none
TEST=make buildall -j
observed 91 .elf files and 89 .smap files generated.
the two images not triggering .smap file generation are
build/npcx_evb/chip/npcx/lfw/ec_lfw
build/npcx_evb/chip/npcx/spiflashfw/ec_npcxflash
they could be added in a follow up patch if deemed necessary.
