[sw] Enable --ffunction-sections and --gc-sections options

The --ffunction-sections option places each function into its own
section while the linker option --gc-sections causes the linker to
delete any unreachable symbols. In combination they can signficantly
reduce the size of the final executable binary.

Removes approximately 4KiB of unused symbols from the mask ROM.
