Testsuite hang on Alpine Linux s390x

[tmh1999]

Hello,

I am building fftw on Alpine Linux s390x and having a hang when running tests check. For reference here is the recipe/script to build fftw on Alpine : https://github.com/alpinelinux/aports/tree/master/main/fftw

The snippet at the end are those last lines before I have to interrupt.

The full log is pretty long so I split them in 2 parts : http://tpaste.us/w7xb, http://tpaste.us/JgR7. Or you can find them at https://gist.github.com/tmh1999/a5faf5286de27873942171252c8d7783, https://gist.github.com/tmh1999/dedb7aa555712e37d0852a73e432df7f.

To reproduce, in your s390x host machine:

s390x-host:/home/user $ sudo docker run -ti alpine:3.7 sh

/ # sed -i -e 's/v3\.7/edge/g' /etc/apk/repositories
/ # apk update && apk upgrade
/ # apk add abuild build-base libressl git
/ # adduser -s /bin/ash -D -g '' builder
/ # addgroup builder abuild
/ # su builder
/ $ echo -e "\n" | abuild-keygen`-a
/ $ cd
~ $ git clone --depth 1 git://git.alpinelinux.org/aports
~ $ cd aports/main/fftw/
~ $ sed -i -e 's/ !s390x//g' APKBUILD
~ $ abuild -r

If you don't have a s390x in hand, IBM LinuxONE Community Cloud provies free VMs.
