clang-3.8 fails to compile inline asm having ldarx with 4 args.
Quoting [1]:
'''
Recent versions of the PowerPC architecture added a hint bit to the larx
instructions to differentiate between an atomic operation and a lock
operation:
> 0 Other programs might attempt to modify the word in storage addressed by EA
> even if the subsequent Store Conditional succeeds.
>
> 1 Other programs will not attempt to modify the word in storage addressed by
> EA until the program that has acquired the lock performs a subsequent
> store releasing the lock.
'''
I also found some more info about this in [2].
Anyway, we could either construct some preprocessor logic to omit this
argument for clang, or just drop it. This patch does the latter.

Since in criu we can't choose proper
arch inside include statements (well,
it will simply require more ifdefs),
I generate include/common/asm symlink
to point proper architecture.
