+Change function type from "extern __inline__" to "static __inline__"
+
+"extern __inline__ function()" is the inlined version that
+can be used in this compilation unit, but there will be another
+definition of this function somewhere, so compiler will not emit
+any code for the function body. This causes problem in -O0,
+where functions are never inlined, the function call is preserved,
+but linker can't find the symbol, thus the error happens.
+
+since no packages provide atomic_add and atomic_sub, and -O0
+Optimize is hoped to keep for debug, we can change extern to
+static to fix this problem.
+
