[yocto] aarch64-oe-linux/bin/ld: cannot find -lgcc . Adding native build support for arm64/aarch64 in oe-rootfs.

[Khem Raj]

you could use multilib add something like this below to local.conf

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