A little catch - this series was developed before the other got merged, so it 
currently conflicts with patch #3 from there. It can be quickly tested by 
reverting patch #3 from the other series, as this expects the use of the 
original EAT_TARGET_SYS and not OE TARGET_SYS. We need to decide what is the 
default. If we decide to default to all prebuilt binaries even for SDK, then 
using EAT_TARGET_SYS is easier and requires less adjustments. But if the 
default should be to rebuild SDK binaries, then maybe defaulting to OE 
TARGET_SYS is fine, as just got merged to master. Either way some extra 
symlinking would be necessary and I can take care of it. Please speak up.
