[Issue]: HIPRTC linking error causes test failure, HIPRTC compile/link behavior seems to have changed

Problem Description

TODOs before releasing 6.1.0 sources (to release/rocm-6.1.0 branch) and binaries to test.pypi.org:

• Investigate hiprtc linker error when testing examples/1_Advanced/hiprtc_linking_with_llvm_ir.py.
