[Buildroot] [git commit] liburcu: only some architectures are supported

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=832b1ef746e7df252ff42b19f6083f3716f70eb9
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Make sure that liburcu (and the packages that select it) cannot be
enabled on the architectures that are not supported. At the moment,
only x86, x86-64, PowerPC and ARM are supported.

[Peter: add armeb as well]
