`--rpath` to GCC's `libstdc++` not added

[tvandera]

Hi,

I'm trying to build Clang-13.0.1-GCCcore-11.3.0.eb easybuild with the --rpath.

It seems the sanity check step fails because the path containing libstdc++.so is not added to RPATH.

From the log file

One or more required libraries not found for /shared/csa/software/Clang/13.0.1-GCCcore-11.3.0/lib64/libclang-cpp.so.13: /shared/csa/software/Clang/13.0.1-GCCcore-11.3.0/lib64/libclang-cpp.so.13: /lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /shared/csa/software/Clang/13.0.1-GCCcore-11.3.0/lib64/libclang-cpp.so.13)

@casparvl Any thoughts on this?

@bartoldeman Might have some input here, I know that at Compute Canada they deliberately don't do this linking.
