[webkit-dev] No buildbot coverage for Mac Debug

[Adam Barth]

Looking into a failure I saw locally on my machine, I noticed that we
don't have any buildbot coverage for the Debug build on Mac.  We used
to cover this configuration with a Leopard bot, but that bot has been
unable to link for a while (we think because of insufficient memory).

Would it be possible to add a Debug builder/tester to build.webkit.org
for Mac on some platform?

Thanks,
Adam
