uBlock seems to block the builder scripts

I ran into this and thought I'd add my 2 cents. uBlock is being triggered by the "/beacon.js" keyword. The uBlock logger shows the following was blocked.

12:26:31        /beacon.js  --  xhr https://modernizr.com/lib/modernizr/feature-detects/network/beacon.js

This results in the following define in the downloaded js.

define("test/network/beacon", function(){});

Unchecking the Beacon API will exclude the beacon call and result in a valid js download. Turning off (click the blue "power" button) uBlock for modernizer.com also fixes this issue. Alternatively, if users don't want to turn off uBlock, they can enable the advanced options and whitelist modernizer.com only.

If you're interested, /beacon.js is defined in the EasyPrivacy 3rd-party filter. Perhaps contacting the authors of uBlock or the EasyPrivacy list may help in whitelisting/excluding your domain.
