The diffutils package provides a replacement for wctypes.h, which
includes the system wctypes.h and then adds some stuff of it's own -- I
think you are hitting the '#if !GNULIB_defined_wctype_functions' in the
replacement file, which expects to be providing iswalnum, etc., and
prototypes them as 'static inline'; the system wctypes.h protypes are
not static.

Not sure why it should be taking that path, could be because these
functions are not provided by libc for poky-tiny (in which case the libc
headers need patching), or could be the detection in diffutils is
broken. As a quick hack, try removing the offending prototypes from the
sysroot wctypes.h.
