remove legacy ABI switches from SVR4 packaging
SVR4 packaging has a number of ways to toggle ABI compliance (or non-compliance), for legacy packages (for non-compliant packages prior to Solaris 2.4).
These are toggled by setting the following in the environment:
No current packages should be requiring these non-compliance workarounds; most of the legacy packages finally failed when Solaris 10 was released in any case.
which would enforce the old 9-character limit for package names; this is completely useless in the modern world.
