Description
Building qtbase for armv6l with GCC 4.9.4 fails at link time with:
/opt/cross/armv6l-meego-linux-gnueabi/include/c++/4.9.4/bits/atomic_base.h:478: error: undefined reference to '__sync_val_compare_and_swap_8'
/opt/cross/armv6l-meego-linux-gnueabi/include/c++/4.9.4/bits/atomic_base.h:500: error: undefined reference to '__sync_val_compare_and_swap_8'
/opt/cross/armv6l-meego-linux-gnueabi/include/c++/4.9.4/bits/atomic_base.h:500: error: undefined reference to '__sync_val_compare_and_swap_8'
The same environment builds Qt 5.5 correctly.
