In order to build beaglebone_qt5 it is necessary to revert commits
b73cde8ff7c8b673c1108a8ae6f4f8838d1123d4. and
1bdceb5d735aad5fbf32b35e3a7f573ecb727e20. Otherwise it fails to build
wit the same error reported here

    http://autobuild.buildroot.net/results/9c7c66f6fd6a409b08c19f80582b1d1659cde601/

qt5wayland also fails to build, with the same error

    /usr/bin/ld: cannot find /usr/lib64/libatomic.so.1.0.0

Notice that in both case it is trying to use the host compiler and linker.
