Same problems as Odroid xu4 optimization release (bug (#6)):
First one when syncing overlayed ports for cubieboard2-arm repository.
Fixed creating a new branch for 3.7 development.
Second one building glibc. Assemble errors with customized CFLAGS (bug (#9)):
export CFLAGS="-O2 -pipe -mfloat-abi=hard -march=armv7ve -mcpu=cortex-a7 -mfpu=neon-vfpv4"
