Openjdk-infrastructure: Debian playbook requires updating for ARM32

[Haroon-Khel]

Per https://github.com/AdoptOpenJDK/openjdk-infrastructure/pull/1523 it was found that the Debian playbook kept crashing on Debian 8.

Currently all I know is that the gcc-7 and g++-7 packages wont install. Will investigate further

This is specific to arm32 - https://ci.adoptopenjdk.net/job/VagrantPlaybookCheck/OS=Debian8,label=vagrant/834/console
x64 is able to install it okay :-)
If we can't find any apt repos that have it, we could use the gcc-7 role already in the Unix playbook, as there is an armv7l gcc750+ccache tarball at https://ci.adoptopenjdk.net/userContent/gcc/

[Haroon-Khel]

In https://ci.adoptopenjdk.net/job/QEMUPlaybookCheck/ARCHITECTURE=arm32,label=vagrant/88/console, gcc7 and g++7 are not installed via the repo, but through the gcc_7 role. However the job failed at the build jdk stage

As a further to @Haroon-Khel 's above comment, based off ci.adoptopenjdk.net, I don't think we build a OpenJ9 JDK11 for ARM32/armv7l . With #1533 , We'll be able to test building a Hotspot JDK.
The gcc_7 role appeared to work in https://ci.adoptopenjdk.net/job/QEMUPlaybookCheck/ARCHITECTURE=arm32,label=vagrant/88/console , as it was able to build Freetype.

Correct - OpenJ9 does not have support for arm32/armv7l

[Willsparker]

As per https://ci.adoptopenjdk.net/job/QEMUPlaybookCheck/ARCHITECTURE=arm32,label=vagrant/92/
It's just Haroon's PR that will be needed to close this issue- However, I'm going to update #1533 so it will make sure that the build-variant isn't openj9 if building arm32.

[Haroon-Khel]

pr is in at https://github.com/AdoptOpenJDK/openjdk-infrastructure/pull/1535

[Willsparker]

With #1535 and #1533 , running one more ARM32 QPC run to make sure we're good. If it passes, we can close this.

Alright, the playbook passed which was the main point of this issue, and it's been able to compile freetype and is halfway through compiling the JDK, so as far as I'm concerned, this issue can be closed :-)
