This allows doing things like LC_ALL=C some_builtin to run a builtin under a different locale, just like is possible with external programs. The immediate reason is that this allows making printf(1) a builtin without breaking things like LC_NUMERIC=C printf '%f\n' 1.2 This change also affects special builtins, as even though the assignment is persistent, the export is only to the builtin (unless the variable was already exported). Note: for this to work for builtins that also exist as external programs such as /bin/test, the setlocale() call must be under #ifndef SHELL. The shell will do the setlocale() calls which may not agree with the environment variables.

There is no toplevel Makefile structure since these tools are not meant to be built as part of the standard system, though there may be individual Makefiles in some of the subdirs.
