* when we get near the limit of the maximum number of TOC entries that can

    be generated for a single object file on AIX, automatically switch to
    an indirection scheme that uses much less TOC entries, but is slower to
    access global variables
  * manually merged infrastructure for target-specific code generation
    switches from JVM branch (-CTxxx switches)
  * -CTsmalltoc switch for AIX that forces the indirection scheme for TOC
    entries from the start in case the automatic one does not conserve
    a sufficient amount (or in case you bump up against the global TOC
    entries limit during linking)
