Bug Description

When trying to run the example files shipped with Ettus UHD driver all we get is an error due to missing files related to RFNoC blocks as shown below:
It looks like the XML files are missing on the package.

I can also confirm this problem. USRPs X310 seem to be unusable with distribution uhd packages due to this issue.

I am using a workaround to be able to use the X310 which is download the missing files manually and copy to the expected location.

$ wget https://codeload.github.com/EttusResearch/uhd/zip/release_003_010_003_000 -O uhd.zip
$ unzip uhd.zip
$ cd uhd-release_003_010_003_000/host/include
$ sudo cp -Rv uhd/rfnoc /usr/share/uhd/
