Improve amd64 detection on sunos
https://github.com/samba-team/samba/pull/208
Description: SunOS may not include x86_64 or amd64 in uname output. Instead, isainfo can be used to determine architecture. SunOS also does not support noexecstack option (to my knowledge) so we skip noexecstack linking check.
