pub fn local_rocm_lib_dir() -> StringExpand description
The system ROCm runtime’s library directory on THIS box, for
ld_library_path_value’s local callers.
flodl-hw resolves it properly ($ROCM_PATH / $HIP_PATH /
$HSA_PATH / /opt/rocm, probing lib and lib64 for the actual
runtime): detection and the loader path MUST agree, or a box passes
the GPU gate on the runtime detection found and then segfaults on
the path a weaker resolution composed. Falls back to the
$ROCM_PATH-or-convention spelling when no runtime is found — the
loader skips a missing path, so the prefix stays harmless.
