Custom build of hostapd

I'm trying to install a customized build of hostapd, but the toolchain is building a default version of hostapd-utils instead of the customized version.

I modified package/network/services/hostapd/files/hostapd-full.config to contain my customizations, ran make world, and installed the built hostapd, hostapd-utils, and hostapd-common on the router. I didn't receive any errors, but hostapd_cli doesn't reflect my customizations.

Anyone have any suggestions? Is there a way to force hostapd-utils/etc. to use a configuration?

Alternatively, I can build hostapd from direct source (non-LEDE) with the toolchain, but that seems too hacky.
