autoconf directory, but these paths need to be relative to the main source directory. Patch originally by Dan Gohman, r67655. Also, cause configure.ac to find absolute paths to LLVM source and object trees. Together, fixes PR1220. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121645 91177308-0d34-0410-b5e6-96231b3b80d8
