build: add version-specific library path for AIX

richardlau · aduh95 · commit b05394ea6a51 · 2024-07-16T12:01:04.000+02:00
Add the version-specific directory containing the C/C++ runtime libraries to `-blibpath` on AIX. This will help link `node` against the correct libraries at run-time when compiled with a different version of the GNU C/C++ compiler without having to manually set a `LIBPATH` environment variable.
