Bug#946110: silx FTCBFS: unsatisfiable cross Build-Depends

[Helmut Grohne]

Source: silx
Version: 0.11.0+dfsg-2
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability

silx cannot satisfy its cross Build-Depends for many reasons. One of
them is sphinx. However, sphinx is only needed for building the arch:all
documentation package, so it should only be required by
Build-Depends-Indep. The attached patch implements that and thus reduces
dependencies for arch-only builds such as cross builds. Please consider
applying it. I used reproducible builds to verify that the artifacts
remain unchanged by the patch.
