This is not a build error. It's just that the resulting code is not
vectorized, but code can still be built and run. That's barely even a
regression given this file has been shipped only 1 day in unstable.

The multiarch path for fortrain includes is actually:
/usr/include/finclude/<multiarch>/

That will break as soon as another architecture add support for math
vectorization. It's therefore better to use the multiarch path to
install the file.
