[gentoo-dev] Retrieve get_libdir path on EAPI 6

[Geaaru]

Hi,

in EAPI 6 get_libdir function is not more available but I currently use
it on my eclass for initialize some metadata.
How can I retrieve environment $libdir path ? With LIBDIR_${cpu}
variable? 

On mgorny post I read that get_libdir function is part of EAPI, but I
don't understand how this means. I use portage-2.3.4.

Thanks in advance
