[Debian-med-packaging] Bug#929275: minimap2 FTBFS on armhf and arm64

[Helmut Grohne]

Source: minimap2
Version: 2.15+dfsg-1
Severity: important
Tags: ftbfs patch
User: helmutg at debian.org
Usertags: rebootstrap

minimap2 fails to build from source on armhf and arm64 due to supplying
-msse2. Unlike many other architectures, this is easily fixable for
armhf and arm64 using the attached patch. Please consider applying it.
