[poky] [PATCH 03/25] gcc: crosssdk unset TARGET_FPU

[Adrian Alonso]

I will redo the patch based on Ilya suggestion,

But I'm not sure if un-setting TARGET_FPU on crosssdk.bbclass would affect
other targets.

Can some one with more background provide me more details if this could
affect other targets.

Regards
