Bug#1095323: scalapack: test results ignored during s390x build

[Graham Inggs]

Source: scalapack
Version: 2.2.2-1
Tags: patch

Hi Maintainer

I've noticed that test results are ignored during the s390x build,
with the following output:

Tests are hardwired to 4 processes. Only 2 processes were used for the
build, so test failures will be ignored.

I've checked the logs [1], and I believe that s390x is the only
release architecture affected in this way.  hurd-* and x32 also use
fewer than four processes for the build, and m68k and sh4 do not run
the tests at all.

You may be able to enable oversubscription and run the tests on s390x
by using a patch similar to the one below.

Regards
Graham
