What makes you think it is picking up the one in toolchain-layer? I don't see 
references to 4.6 in the QA error. If you haven't added meta-
openembedded/toolchain-layer to your bblayers.conf specifically it won't be 
being seen by bitbake at all.

It's more than likely that this QA error is bogus. The "found library in wrong 
location" QA check was broken originally; I "fixed" it but I think it has 
always been a little over-zealous since then.

Cheers,
Paul
