builds.pm in master has to wait for the actual release.
This reverts the builds.pm part of d5859c6 (which was accidentally pushed too soon) to avoid having the website link to nonexistent files. The modifications need to be re-done as soon as 3.11.1 is actually on the server. Change-Id: Ifee2ed497ffcaefe32b75fa25d829cf0c7b6d17d
