[PATCH] Don't run personality syscall at configure time; don't check it at all

Pedro> Would it work to just include both?

No, they both define the same enum constants, so I think this wouldn't
work.

Pedro> Otherwise, do we really need the configure check?  Wouldn't just:

Pedro> #ifndef ADDR_NO_RANDOMIZE
Pedro> # define ADDR_NO_RANDOMIZE 0x0040000
Pedro> #endif

Pedro> work the same?

They neglected to use the self-#define trick for these constants.
