I was wondering this too but in the opposite direction -- why build
everything for i686 by default if we're only updating the compiler flags
to i586?
Jakub's email sparking this Feature listed the major benefit from
getting new instructions with -march=i486. He then listed additional
helpful instructions when using -march=i586. Nothing listed for
-march=i686.
