Adding ‘introspection’ to polkit USE-flags solves the issue.
It appears to be missing a gobject-introspection-common buildtime dependency for having access to the necessary m4macros (only needed if eautoreconf'ing, which is currently done for elogind patch). Enabling introspection pulled it in and thus eautoreconf started to succeed, irrespective of the actual USE flag effect to the build process other than the dependency.
