This case is okay (if user wants it, don't prevent them do so).

What makes it depend on gcc ?

-a means RB_ASKNAME commonly, though couple of ports use it to mean "autoboot"
(alpha, atari from those I can name off my head).
In flag handling code, the port specific flag handling goes first
and boot_flag() is used only for previously unrecognized flags.

There is already previous art WRT this in FreeBSD and I belive BSDi.
It also hides an implementation details a bit and is slighly more
obvious.
