FreeBSD only works on Sparc64 and freeBSD code relies on the __sparc64__ define.
gcc only defines __sparc64__ if -mcpu is not used.
gcc-4 defaults to using -mcpu=ultrasparc on FreeBSD.
This causes us a problem. Infact, FreeBSD developers sent gcc a patch to always
define __sparc64__ when using -mcpu=ultrasparc, but this was rejected by most
people including NetBSD developers.
The correct solution is to use __sparc__.
If platform detection is required, or the code is obviously 64 bit then we can
use the __arch64__ define as well.
This combination should be supported by all gcc versions:)
