Simon Marchi cbbbc402e0 libctf: mark swap.h inline functions as static 
When building binutils with mingw-w64, I get the following errors:

Apparently [1], if we have a function with `inline` but not `static`,
there should be a compilation unit defining the symbol too.
Alternatively, making those functions `static` fixes that.
