[phenixbb] [cctbxbb] Deprecating legacy support (CentOS 5, Windows 32-bit) in CCTBX and Phenix

[Billy Poon]

Hi Luc,

With the planned migration to conda for dependencies, the idea is to build
one linux installer using the compilers in conda (currently GCC 7.2,
https://conda.io/docs/user-guide/tasks/build-packages/compiler-tools.html) and
then test that installer on multiple distributions of linux. CentOS 7 would
be one of the distributions used for testing.

Or do you need something sooner? We currently do not build our installers
on CentOS 7, but I have checked that the CentOS 6 installer runs and that
the regression tests (phenix_regression.test_all_parallel, which is a
superset of cctbx regression tests) pass on CentOS 7.
