Bug#886421: python-escript: FTBFS on m68k: hwloc_set_cpubind returned "Error" for bitmap "0"

[Aaron M. Ucko]

Source: python-escript
Version: 5.1-5
Severity: important
Tags: upstream
Justification: fails to build from source (but built successfully in the past)
User: debian-68k at lists.debian.org
Usertags: m68k

Builds of python-escript for m68k (admittedly not a release
architecture) have been failing lately per the below excerpts from
https://buildd.debian.org/status/fetch.php?pkg=python-escript&arch=m68k&ver=5.1-5&stamp=1514854858&raw=0.
FWIW, automatic builds for this architecture run with nocheck in
DEB_BUILD_OPTIONS because there's little overall incremental value to
running tests on such a slow architecture.  However, it's perhaps just
as well that that setting had no effect here, since this problem
doesn't affect any other Debian architectures and may be worth
investigating.

Could you please take a look?

Thanks!

WARNING: a request was made to bind a process. While the system
supports binding the process itself, at least one node does NOT
support binding memory to the process location.

Open MPI uses the "hwloc" library to perform process and memory
binding. This error message means that hwloc has indicated that
processor binding support is not available on this machine.
