BUG: Inlined functions must be defined somewhere.
BUG: Inlined functions must be defined somewhere.

Some inline functions in numpy/core/src/multiarray/mapping.c were
defined as `NPY_NO_EXPORT NPY_INLINE` with the result that gcc 7.1 was
looking for an external definition. Possibly some of those functions
were no longer being inlined. The fix was to replace `NPY_NO_EXPORT`
with `static`. A grep of the numpy source files turned up no further
uses of that unfortunate combination.
