This makes sure that our local copy of libclang.dylib is preferred over the
system one.

# Things are a bit different on Macs when using an external libclang.dylib; here
# we want to make sure we use @loader_path/libclang.dylib instead of
# @rpath/libclang.dylib in the final ycm_core.so. If we use the @rpath version,
# then it may load the system libclang which the user explicitely does not want
# (otherwise the user would specify USE_SYSTEM_LIBCLANG). With @loader_path, we
# make sure that only the libclang.dylib present in the same directory as our
# ycm_core.so is used.
