From dd464df687faf544e83684d0c0e4da87c05f8bfe Mon Sep 17 00:00:00 2001

Subject: Add new configure option, --disable-timestamps, intended to turn off
 anything which would mess up binary/object comparisons. Currently:  -
 Disables 'Built on ...' in 'foo --version'.  - Disables timestamps from being
 embedded into .dir files.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103423 91177308-0d34-0410-b5e6-96231b3b80d8
