Add a sectalign directive for Segment
and Section
to the maximum expected page size for Darwin.
On iPhone 6+ the max supported page size is 16K. On macOS, the max is 4K. Use a common alignment constant (16K) for now, and reduce the alignment on macOS if it proves important.

Returns the most appropriate macOS target version for the current process.
If the macOS SDK version is the same or earlier than the system version, then the SDK version is returned. Otherwise the system version is returned.

Pass -no_deduplicate to ld64 under certain conditions:
Also do not add -no_deduplicate when no -O option is specified and this is just a link (we can't imply -O0)
