Deprecate in-source autotools builds
This is a followup from:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20150323/268067.html
Upgrade instructions:
$ mv llvm/include/llvm/Config/config.h ./config.h.BACKUP
# copy the configure line from line 7 of llvm/config.log
# (for example: `$ ./configure --no-create --no-recursion`)
$ mkdir build
$ cd build
# run the configure line, but this time with '../llvm' at the beginning:
$ ../llvm/configure --no-create --no-recursion
These warnings will soon be turned into hard errors after a week. Speak up now
if this is going to be a problem for you.
