[Xastir] Kubuntu _and_ Raspberry Pi build fails

[vk2tv]

Lee,

I uninstalled libwebp-dev on my Debian Jessie installation and ran 
./configure for xastir. It reported the Imagemagick/Graphicsmagick error.

I reinstalled libwebp-dev and again ran ./configure. This time there 
wasn't an error and all options said YES.

Regards,

Ray vk2tv
