Stop using devtoolset-2 to provide GCC4.8

[sxa]

DRAFT as I don't necessarily want to merge this, but I want to see if it unblocks the playbook execution on CentOS6 (Let's Encrypt failure from people.centos.com)

I don't think 4.8 is needed any more for any releases, as the lines that used it (JDK8/J9/s390x) are superceded by later directives in build.sh

Looks like the unarchive module doesn't work with the problematic certificates so this isn't going to work sadly ...

Superceded by #2344 in order to resolve the certificate problem, but we should considere whether we still need GCC4.8 on the machines going forward.

Closing as #2344 was ultimatley a preferable solution here.
