[yocto] libatomic missing in krogoth Yocto 2.1

[Joel Zhou]

Hi all,

I'm building core-image-minimal with Yocto 2.1 krogoth.
It failed with missing libatomic. The only thing closest is libatomic-ops.
meta/recipes-support/libatomic-ops/libatomic-ops_7.4.2.bb

[joelz at ldt-joelz]:(krogoth)$ bitbake core-image-minimal

Any suggestion?
