Fix "quiet inline" configure test for newer clang compilers.

This test used to just define an unused static inline function and check
whether that causes a warning.  But newer clang versions warn about
unused static inline functions when defined inside a .c file, but not
when defined in an included header, which is the case we care about.
Change the test to cope.
