In the Debian rules file one can see that --no-force-sse2 is enabled for platforms which never have sse2 eg armhf

There should be a test eg grep sse2 /proc/cpuinfo for i386 and amd64 to see if sse2 is available, and if not, then the --no-force-sse2 should also be added to the build options.

Why has the maintainer of the package not responded to this bug in nearly 2 years with this simple fix?
