Properly mark all internal function definitions.

Since we banned old style function definitions GCC is able to diagnose
function definitions that don't match the function declaration:

  elf32_getehdr.c:78: error: conflicting types for ‘__elf64_getehdr_wrlock’
  libelfP.h:498: note: previous declaration of ‘__elf64_getehdr_wrlock’

This happens on i386 because there internal functions are marked with:

  # define internal_function __attribute__ ((regparm (3), stdcall))

Make sure all internal function declarations and definitions are marked
with internal_function.
