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. 2019-01-21 18:47:57 -06:00			`(cd $(TMPDIR); $(LD_LIB_PATH_ENVVAR)=$(REAL_LD_LIBRARY_PATH) llvm-ar x ./staticlib.a)`
