-Subject: [PATCH] Workaround presence of LLVM library in stage0/lib
-
-This commit works around the newly-introduced LLVM shared library.
-
-This is needed such that llvm-config run from
-librustc_llvm's build script can correctly locate it's own LLVM, not the
-one in stage0/lib. The LLVM build system uses the DT_RUNPATH/RUNPATH
-header within the llvm-config binary, which we want to use, but because
-Cargo always adds the host compiler's "libdir" (stage0/lib in our
-case) to the dynamic linker's search path, we weren't properly finding
-the freshly-built LLVM in llvm/lib. By restoring the environment
-variable setting the search path to what bootstrap sees, the problem is
-resolved and librustc_llvm correctly links and finds the appropriate
-LLVM.
-
-Several run-make-fulldeps tests are also updated with similar handling.
