predefine __ATOMIC_ACQUIRE & friends as weak
In kernel's arch/mips/Makefile the whole content of gcc's -dM is used
for CHECKFLAGS. This conflict with some macros also defined internally:
builtin:1:9: warning: preprocessor token __ATOMIC_ACQUIRE redefined
builtin:0:0: this was the original definition
Fix this by using a weak define for these macros.
