    [SV 63417] Ensure global .NOTINTERMEDIATE disables all intermediates
    
    Fix .NOTINTERMEDIATE without prerequisites to disable intermediate
    status for all targets.
    
    * src/makeint.h: Declare extern no_intermediates.
    * src/main.c: Add global definition of no_intermediates.
    * src/file.c: Remove static no_intermediates to use global variable.
    (remove_intermediates): Check no_intermediates.
    * src/implicit.c (pattern_search): For a file found by implicit search
    set file->notintermediate if no_intermediates is set.
    * src/remake.c (update_file_1): Don't set file->secondary for a
    pre-existing file if no_intermediates is set.  The check for
    no_intermediates here is redundant, but won't hurt: keep it in case
    things change so that it matters.
    * tests/scripts/targets/NOTINTERMEDIATE: Fix a test.

    [SV 63347] Always add command line variable assignments to MAKEFLAGS
    
    This commit introduces two visible changes:
    1. Keep command line variable assignments in MAKEFLAGS at all times,
       even while parsing makefiles.
    2. Define makeflags immediately when a makefile modifies MAKEFLAGS.
    
    The new MAKEFLAGS and MAKEOVERRIDES initialization procedure:
    1. decode_switches (argc, argv, o_command) is called to parse command
       line variable assignments.
    2. Command line variable assignments go through quote_for_env.
       Initialize -*-command-variables-*- to the quoted values.
    3. MAKEOVERRIDES is initialized to refer to -*-command-variables-*-
       with origin o_env to keep the definitions in the database intact.
    4. define_makeflags() is called which adds MAKEOVERRIDES to MAKEFLAGS.
    5. Makefiles are parsed.  If a makefile modifies MAKEFLAGS, the new
       value of MAKEFLAGS is defined right away.
    6. Env switches are decoded again as o_env.  The definitions set by
       decode_switches at step 1 stay intact, as o_command beats o_env.
    
    We must preserve the original intact definitions in order to detect
    failure cases; for example:
      $ cat makefile
      all:; $(hello)
      $ make hello='$(world'
      makefile:1: *** unterminated variable reference.  Stop.
    
    * src/makeint.h: Declare enum variable_origin, struct variable and
    define_makeflags().  Add parameter origin to decode_env_switches().
    * src/main.c (define_makeflags): Remove "all". If a variable is
    assigned on the command line then append MAKEOVERRIDES to MAKEFLAGS.
    (decode_env_switches): Replace parameter env with origin.
    (decode_switches): Replace parameter env with origin.
    Treat origin == o_command as env == 0.
    (handle_non_switch_argument): Replace parameter env with origin.
    Treat origin == o_command as env == 0.
    (main): Call decode_switches() with origin==o_command before parsing
    makefiles.  Call decode_switches() with origin==o_env after parsing
    makefiles.
    * src/variable.c (set_special_var): Define makeflags at parse time,
    each time a makefile modifies MAKEFLAGS.
    (do_variable_definition): Strip command line variable assignments from
    MAKEFLAGS before appending extra flags.  set_special_var() adds them
    back.
    * tests/scripts/variables/MAKEFLAGS: Add tests.
