commit: https://git.buildroot.net/buildroot/commit/?id=f1450e9084b3c43f82497ae8254c7dca2fecc049
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x

Qt5Multimedia builds the alsa plugin if it detects libasound in the
system. Add alsa-lib to dependencies if BR2_PACKAGE_ALSA_LIB is
selected.
