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

It install 4.6.3 fine. However 4.7.2 fails in libgcc install with

config.log attached.
Any idea how to fix?
Did you look in config.log?
It shows the problem is:
conftest.c:1:0: sorry, unimplemented: -mfloat-abi=hard and VFP
Have you tried without that combination?
