Add test case for including upstream object files in staticlibs when doing cross-lang LTO.

-include ../tools.mk
# This test makes sure that we don't loose upstream object files when compiling
# staticlibs with -Zcross-lang-lto
all: staticlib.rs upstream.rs
$(RUSTC) upstream.rs -Z cross-lang-lto -Ccodegen-units=1
# Check No LTO
$(RUSTC) staticlib.rs -Z cross-lang-lto -Ccodegen-units=1 -L. -o $(TMPDIR)/staticlib.a
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.
