[gentoo-dev] [PATCH] multilib.eclass: add initial defaults for ARCH=loong

[gentoo-dev] [PATCH] multilib.eclass: add initial defaults for ARCH=loong

[WANG Xuerui]

From: WANG Xuerui <git@xen0n.name>

There is only full support for the LP64D ABI in the initial upstream
submissions for the various low-level pieces, so full multilib
combinations are not pursued at the moment; but the expected library
search path of gcc (`lib64`) means the default of `lib` does not work
in our case.
