The merging of next -> master was announced for UHD, not for GNU
Radio. You need:
UHD master branch
GNU Radio next branch

next branch is (was earlier today) v3.3.1git-865-gd429522

Aside from using the correct GNU Radio branch (next) you also need to
install UHD first, otherwise the GNU Radio configure script will not
detect it and will skip it.
