Merging r195834:
------------------------------------------------------------------------ r195834 | whitequark | 2013-11-27 03:03:18 -0800 (Wed, 27 Nov 2013) | 11 lines [OCaml] Embed rpath into stub libraries and native executables This commit embeds a set of linker flags with hardcoded paths to the LLVM shared library on --enable-shared builds into .cmxa files and stub dynamic libraries. This solution closely follows existing rules for rpath in the LLVM tools, which had to be modified because of differences in toolchain. Without this patch, OCaml tests as well as opam bindings broke, as neither of those updates LD_LIBRARY_PATH to include the $prefix/lib directory. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195873 91177308-0d34-0410-b5e6-96231b3b80d8
