Or pass in the appropriate flags to configure. My configure invoking
script has: LDFLAGS='-Wl,-rpath,/home/andres/build/llvm/6/opt/install/lib' etc
in it.

I'm not sure we want to do that - and if so to which libraries. I tend
towards thinking that if we do that, we should do it uniformly, not just
for LLVM. At the very least it'd have to respect --disable-rpath.

I only see one copyright year related diff. Perhaps you're using a
patched distribution autoconf?
