 Rework sysconf flags to fit new scheme.

 The old method of deriving sysconf wrapper needs from ifndefs was
 incompatible with SDK flexibility.  This sets up the usual SDK/lib
 flags, referenced to the appropriate OS versions (and the i386 fix).

 See: https://trac.macports.org/ticket/69867

 TESTED:
 Builds and passes tests on all platforms.
