Bug#875847: qttools5-dev-tools: .qhc files not reproducible

[Chris Lamb <lamby@debian.org>]

Hi Laurent,

Curiously, I don't see that when I build locally. But I *do* see:

  - The buildpath being leaked into ".index" files. This is fixed with
    the attached patch.

  - Some variation in the binary, not looked into.

Hope that helps a little.


Best wishes,
