What i committed for 3.5 and 3.6 matches lto-cpython3-v04.patch which just adds --with-lto support.  2.7 still needs to be patched.

For reference: Using ubuntu's gcc 5.2.1 i was seeing a 2-3% performance increase in the resulting LTO binary vs a plain profile-opt PGO build.  That'll vary based on arch and compiler toolchain.
