* Remove autoconf supportChris Bieneman2016-01-261-2/+0
| | | | | | | | | | | | | | | | Summary: This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "I felt a great disturbance in the [build system], as if millions of [makefiles] suddenly cried out in terror and were suddenly silenced. I fear something [amazing] has happened." - Obi Wan Kenobi Reviewers: chandlerc, grosbach, bob.wilson, tstellarAMD, echristo, whitequark Subscribers: chfast, simoncook, emaste, jholewinski, tberghammer, jfb, danalbert, srhines, arsenm, dschuff, jyknight, dsanders, joker.eph, llvm-commits Differential Revision: http://reviews.llvm.org/D16471 llvm-svn: 258861
