In header file, "extern inline" may cause multiple definition, so need
change it to "static inline". And also need be quoted by __GNUC__ for
they are as inline functions only for __GNUC__.
The related error (with allmodconfig under tile):

Why not remove the #define and use static inline
in the 4 places the #define is currently used?

I just follow the original author's ways, the original author may think
it is useful.
I guess, it may be used by other systems (neither Linux kernel nor gcc).
For another compiler, it may need another syntax for it (although I am
not quite sure about it).
So for safety reason, still keep it no touch, at present.
Thanks.
