ld: Add --no-print-map-discarded option
Add a new option to disable the listing of discarded sections
in map file output. The use case stems from a large application
built with -ffunction-sections --gc-sections where the list of
discarded sections blows up the map file output. The default
behaviour remains to print discarded sections, but the new option
allows us to disable it.
