Since r154114 which introduced ldconfig_local32_dirs, ldconfig -32 was called with -m. This means that ld32.so.hints paths set is not cleared for compat32 on boot, unlike ld,so,hints.
The patch fixes the asymmetry, I am not sure if this just a typo or there was some rationale behind the difference.
