Bug#1067582: gnuplot: please provide a profile to break B-D cycle

[Dima Kogan]

Hi.

I might be misunderstanding what you're asking specifically, but two
notes:

- Today leptonlib Build-Depends on gnuplot-nox only if !nocheck. So if
  you build leptonlib with testing disabled, there's no dependency on
  gnuplot

- Today the gnuplot source package has a hard Build-Depends on wxt and
  qt. Removing either of those (even in a specific profile) would make
  it impossible to build gnuplot-qt and gnuplot-x11 packages with the
  same set of functionality they normally have. If a profile was added
  to loosen either of these dependencies, but that dramatically changed
  the end product, would that be useful?

Thanks
