[f16-branch][master] GPT blacklist for known-broken BIOSes

[David Lehman]

Don't even try to use GPT on Lenovo systems. It's 2011, you say?

[PATCH] Don't use GPT disklabels on Lenovo BIOS systems. (#749325)

[David Lehman]

Lenovo ships broken BIOSes that cannot boot at all if the
only disk has a GPT disklabel.
