4.7.2 install fails on Raspberry Pi

[Bela Markus]

Hi,

yes I found it on config.log and already running install without these 
options. Native build takes 6 hours, will see the result a bit later. I 
already tried and failed, it's a new run. However 4.6.3 installs fine so 
it's a different behavior in 4.7.2

Thanks... Bela
