[PATCH] bitops: alpha: use config options instead of __alpha_fix__ and __alpha_cix__

Browse Source 
Use config options instead of gcc builtin definition to tell the use of
instruction set extensions (CIX and FIX).

This is introduced to tell the kbuild system the use of opmized hweight*()
routines on alpha architecture.
