Bug 315130 – Fix run-minibrowser/run-swiftbrowser crash on argparse 'const' kwarg

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[zak ridouh]

run-minibrowser and run-swiftbrowser translate each optparse Option from
configuration_options() / platform_options() into an argparse add_argument()
call, and were unconditionally forwarding const=option.const. That worked
while every option used action='store' or 'store_const' (both accept const),
but 313522@main added --cmake with action='store_true'. argparse's
_StoreTrueAction.__init__ does not accept a const keyword, so the loop now
raises:

    TypeError: __init__() got an unexpected keyword argument 'const'

before the parser is even built, breaking both scripts at startup.

Only forward const= for the actions that accept it (store_const,
append_const). All other options keep their previous behavior.
