- 
- cross-compilation personality support:
- 
-   --personality=triplet|filename    sets the personality to 'triplet' or a file named 'filename'
-   --dump-personality                dumps details concerning selected personality
-

-   --shared                          use a simplified dependency graph (usually default)
-   --pure                            optimize a static dependency graph as if it were a normal
-                                     dependency graph
