Could a compiler #define such as "-DBUILTIN_LED=LED_BUILTIN" and remove the need for all these repeated 2nd #define BUILTIN_LED X?

BUILTIN_LED is not used in core, but seems to be historically used in esp8266 code outside.
What about moving this define into variants/generic/common.h (hidden, wrong name less exposed, less loaded gcc cmdline) ?

If it's not standard, how about putting it somewhere safe and deprecating its use?

Right. BUTTON_BUILTIN added, commented BUILTIN_* removed.
deduplicate and hide BUILTIN_LED as a deprecated constant

Arduino only defines LED_BUILTIN, should BUILTIN_LED be removed ?
