As the conditionals and targets was becoming quite hard to

This commit fixes that while restructuring the Makefile so that

This is similar to the Windows change at

When a `Module` is created with `enable_multiple_field_` = true,
all FUNCs and PUBLICs that share the same address will be collapsed
into a single entry, and that entry will be marked with `m` for
multiple in the final output.
`enable_multiple_field_` is temporary just in case people are
depending on the current behavior.
Support for `dump_syms` executables will be added in a follow-up.
