OK for trunk and release branches?

As shown in the PR, the default is not UTF-32 but rather UTF-32BE or
UTF-32LE, avoiding the need for a byte order mark in literals.

@opindex fwide-exec-charset
@cindex character set, wide execution
Set the wide execution character set, used for wide string and
-character constants. The default is UTF-32 or UTF-16, whichever
-corresponds to the width of @code{wchar_t}. As with
-@option{-fexec-charset}, @var{charset} can be any encoding supported

+big-endian or little-endian byte order being used for code generation. As
+with @option{-fexec-charset}, @var{charset} can be any encoding supported
by the system's @code{iconv} library routine; however, you will have
problems with encodings that do not fit exactly in @code{wchar_t}.
