readelf_wi_test checks the DW_AT_LANGUAGE is recognized by matching
against ANSI C. But for the new DWARF5 DW_LANG_C11 readelf simply
prints "C11", not prefixed with ANSI (DW_LANG_C is "non-ANSI C",
DW_LANG_C89 is "ANSI C" and DW_LANG_C99 is "ANSI-C99"). Adjust the
testcase instead of readelf because C11 seems a fine name.
binutils/ChangeLog:
* testsuite/binutils-all/readelf.exp (readelf_wi_test): Also
recognize DW_LANG_C11.
