x86: disable X86_PTRACE_BTS for now
Oleg Nesterov found a couple of races in the ptrace-bts code and fixes are queued up for it but they did not get ready in time for the merge window. We'll merge them in v2.6.31 - until then mark the feature as CONFIG_BROKEN. There's no user-space yet making use of this so it's not a big issue.
