125b7c8cbb In shell scripts run during the build, add a SED variable, defaulting 
to "sed".  SED=${TOOL_SED:Q} should be passed in the environment to

9577284633 Don't try to remove trailing newlines from shell variables via 
constructs like ${var%$nl}.  Apparently this allows the Ubuntu Linux
/bin/sh (dash) to be used as a host shell during the build.
Patch from PR 39786 by Andy Shevchenko.

7fb5a8c68e The field width passed for a %.*s printf format is supposed to be int, not 
ptrdiff_t; on 64-bit platforms the latter will be too wide.
Adjust accordingly.

72c2627f1f Wrap declaration of a STATIC function that's only conditionally defined 
in a suitable ifdef, so things still compile if STATIC is defined as
"static", which is for some reason not the default.

744c8edc4b Wrap declaration of a STATIC function that's only conditionally defined 
in a suitable ifdef, so things still compile if STATIC is defined as
"static", which is for some reason not the default.

(In the long run STATIC should go away - it might have once been a
portability hack but now definitely serves no purpose.)

cd12700971 If SHELL_BUILTIN is defined (as will be the case when building external 
builtins such as the printf command), then hide a few declarations.

This allows the shell to build again, fixing a problem with
"error" being declared as a function here, and as a variable in
.../usr.bin/printf/printf.c.

d6d9ccc8ad * define SHELL_BUILTIN, which other headers may use to hide some of their 
symbols if appropriate.  For example, error.h will use it to hide
  declarations that should not be seen by external builtins such as printf.
* The shell's outfmt() function returns void, but the standard fprintf()
  function returns int.  Similarly for several other functions that are
  redefined via macros in bltin.h.  Add a _RETURN_INT macro to do the
  necessary conversion.
* Delete some declarations that appear in error.h.
* Add comments on some #else/#endif lines.
