Dear Reviewers,

Following several previous communications, this pull request enables compilation of cpython with lto only optimization. While configure’s flag --with-lto is to be used, a new make target has been added: make build_all_lto .

I am looking forward to receive feedback from you.

Best regards,
Octavian

There is an update I am working for adding lto only compilation option. Please let me add this modification before spending any additional time in reviewing the previous commit.

Enabling separate lto only compilation mode helps the trade-off
capabilities between required compilation time and optimization
results. Moreover, it enables studies of performance on different
platforms.
