Dana Robinson 8bbdc947c4 [svn-r28972] Removed option to clear file buffers from autotools, CMake, and library.
Buffers that will be written to disk will now always be cleared since
not doing this has huge security implications.

Tested on: 64-bit Ubuntu 15.10 (Linux 4.2.0, x86_64) gcc 5.2.1
           serial autotools
           parallel autotools (MPICH 3.1.4)
           serial CMake
