Look at debian/rules and see what they're doing with regards to build-time config options.
The config options in the xmbc SlackBuild has --enable-neon
Assuming this means enable NEON instructions, then you're going to have a problem with that since the RPi doesn't support them.
Try removing that and looking at the other options that Ubuntu have - such as disabling GLES.
If that doesn't work, ask on the XBMC list -- a 5 second google search shows you're not the only person to have this exact problem.
