Description Robert Yang 2015-11-04 13:31:48 UTC 
Currently when building multilib for aarch64:

MACHINE = qemuarm64
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "armv7at-neon"

$ bitbake core-image-minimal -cpopulate_sdk

WARNING: gcc multilib setup is not supported for TARGET_ARCH=aarch64
WARNING: gcc multilib setup is not supported for TARGET_ARCH=aarch64

We need make it build and run well.

I suspect ilp32 will be added at some point.

Hello,

Verified on latest master: f98e11c80951d39401d7caef8f8324969547b246.
cooker log looks well, all lib32 related targets were successful. 

No more warnings.
