## edd 24 Oct 2003  build is invoked by the buildd, so we would prefer to
##		    not imply build-indep; unfortunately R does not build
##		    properly without it, so we have to stick with it
## edd 15 Jan 2004  trying again on build only build: build-arch build-indep
##		    the main hook is to then have binary depend on both
##		    binary-arch and binary-indep, and those on their builds
## edd 19 Sep 2019  for source uploads also build build-indep
