Observed in libtool-2.4.2:

libtool warns about moved paths, yet, libtool was the one that added
the compiler-specific
/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64 into the
command line in the first place.

/bin/sh ./libtool  --tag=CXX   --mode=link g++  -g -O2   -o libx.la -rpath /usr/local/lib x.lo -lxml2

What was expected instead:
Perhaps not use -nostdlib -L/usr/lib64/... and just let CXXLD do that itself
internally.
