[Antonio Terceiro]

Control: clone -1 -2
Control: reassign -2 gem2deb
Control: retitle -2 gem2deb: includes architecture qualifiers in ${ruby:Depends}

This happens because the mapping between Rubygems package names and
Debian packages sometimes will include an architecture qualifier,
because it uses the output of dpkg -S. I'm not sure why it doesn't
happen for all arch:any packages, though:

$ dpkg -S /usr/share/rubygems-integration/*/specifications/* | grep ruby-thrift
ruby-thrift:amd64: /usr/share/rubygems-integration/2.7.0/specifications/thrift-0.14.0.gemspec
ruby-thrift:amd64: /usr/share/rubygems-integration/3.0.0/specifications/thrift-0.14.0.gemspec
$ dpkg -S /usr/share/rubygems-integration/*/specifications/* | grep ruby-ffi:
ruby-ffi: /usr/share/rubygems-integration/2.7.0/specifications/ffi-1.12.2.gemspec
ruby-ffi: /usr/share/rubygems-integration/3.0.0/specifications/ffi-1.12.2.gemspec

gem2deb needs to be modified to strip the architecture off the package
name, and then ruby-jaeger-client needs to build depend on a new version
of gem2deb that contains the fix.
