large in the case of the gamma function; I would say this is such an
elementary function that it should really be correct up to the last one or
two bit. Hence it would also be reasonable to decide that these are
really bugs in whichever library this is implemented in on ARM, and hence
should keep giving doctest failures on ARM.

If I understand correctly (from your comments on this tickets and
[https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/713985 here]) the
failure arises because of a bad eglibc implementation of `lgamma` (log
gamma), so it should really be fixed upstream.
Now I just noticed on [http://www.eglibc.org/] that eglibc is no longer
maintained. Is it recommended to use the normal glibc on ARM nowadays,
and does the bug also exist there?
