 - [ ] debian7 needs to update alternative gcc/g++
 - [ ] verify that /usr/local/bin works as ccache install path
 - [x] remove subversion since v8 tests uses git nowadays
 - [ ] assign 192/256mb ram to the jenkins instances that requires it:
       - aix

 - [x] make .ssh/config and .ssh/id_rsa for release machines, adding config
       for `node-www` and record host key for node-www
