compile/opt: add config DEBUG_LINK_MAP

Selecting this option will pass "-Map=$(TOPDIR)$(DELIM)nuttx.map" to ld when linking NuttX ELF. That file can be useful for verifying and debugging magic section games, and for seeing which pieces of code get eliminated with DEBUG_OPT_UNUSED_SECTIONS. Signed-off-by: chao.an <anchao@xiaomi.com>
