[Debian-med-packaging] Bug#983631: blasr FTCBFS: multiple reasons

[Helmut Grohne]

Source: blasr
Version: 5.3.3+dfsg-5
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability ftcbfs

blasr fails to cross build from source. The immediate issue is failing
to install python3 for the host architecture. Indeed, blasr does not
need a host architecture python, it merely wants a runnable (i.e. build
architecture) python for ./tools/git-clang-format. That can be requested
using python3:any or python3:native. Beyond this, it fails to pass a
suitable crossfile to meson. The easiest way of doing so is using
dh_auto_configure. Please consider applying the attached patch to make
blasr cross buildable.
