Package libiwinfo required! - but it is there!?

[n8bs]

Router TRENDnet TEW-691GR (TEW-692GR is also affected)
I'm running the LEDE snapshot image 2016.08.20 and have installed luci-ssl.
In the gui I cannot enable wlan.
In Network -> Wireless it says in a yellow box:
Package libiwinfo required!
The libiwinfo-lua package is not installed. You must install this component for working wireless configuration!

But from opkg it looks like it is there allready.
root@lede:~# opkg install libiwinfo-lua
Package libiwinfo-lua (2016-07-04-96d322d5941c57be58f8e8d5c6e2b28e90ed3598) installed in root is up to date.
root@lede:~# opkg install libiwinfo
Package libiwinfo (2016-07-04-96d322d5941c57be58f8e8d5c6e2b28e90ed3598) installed in root is up to date.

I tried reflash an install non-ssl luci. Same problem.

EDIT:
I'm on LEDE Reboot r1399 / LuCI Master (git-16.232.29304-c0af360)
Configured wireless from commandline without any issues but in luci I get Package libiwinfo required!

@jow- The error is related to the new shared build and the fact that mipsel_74kc is used by brcm47xx and ramips/rt3883. Therefore the wl iwinfo backend will be included for the rt3883 devices without having the wl kmod(?) installed.

Long story short, libiwinfo needs a PKG_FLAGS:=nonshared.

I've received the following output from one of the affected user:

Spot-on, @mkresin :) I pushed a fix to the tree. See https://git.lede-project.org/885910
