Bug#851162: FTBFS: issues with longdouble precision on ppc

[Ghislain Antony Vaillant]

Package: src:h5py
Severity: serious
Justification: fails to build from source (but built successfully in the past)
Usertags: ppc64el

Dear Maintainer,

The recent release of h5py FTBFS on powerpc-based architectures due to
test failures regarding long-double precision.

Upstream has been notified but fails to find where the origin of the
issue is. Some help from ppc experts would be appreciated. The latest
build log is available here [1].

Regards,
Ghis
