[PATCH] oeqa/sstatetests: Add test for nativesdk stamp invariance with MACHINE

[Richard Purdie]

nativesdk-glbic should not rebuild when you change MACHINE but
it was. We've fixed that, now add tests to ensure this doesn't
happen again.

Rather than add yet another stamps test, extend one of the 
existing ones to cover this instead.
