atlas: second level name cpufamily in hw.cpufamily is invalid

[ryandesign@…]

The atlas port is unusable on Tiger (cannot install, cannot upgrade, cannot get info, etc.) because the port indiscriminately calls sysctl hw.cpufamily which is not available on Tiger.

$ sudo port -u upgrade atlas
Error: Unable to open port: second level name cpufamily in hw.cpufamily is invalid
To report a bug, see <http://guide.macports.org/#project.tickets>

This was caused by r82290.

This is not hard to fix, but I have no Tiger system to test. BTW, do we still support Tiger?

[ryandesign@…]

If we can fix it easily, it would be nice to do so. MacPorts base still works on Tiger so if ports can still work there, that's nice for users who for whatever reason don't upgrade.

The comment for r82290 mentioned Snow Leopard specifically. So if the code is irrelevant to earlier systems, then perhaps you can only run the check on Snow Leopard.

Fix in r82585. Please update & try again.
