Bug#979031: glslang FTCBFS: python3 dependency not installable

[Helmut Grohne <helmut@subdivi.de>]

Source: glslang
Version: 8.13.3743-1
Tags: patch
User: debian-cross@lists.debian.org
Usertags: cross-satisfiability

glslang cannot be cross built from source, because its build dependency
on the host architecture python3 is not installable. It actually wants
to run python3 during build though, so what it really needs is a build
architecture python3. Once tagging it with :native, it cross builds
successfully. Please consider applying the attached patch.
