Yes, that is a reasonable strategy once there is a stable toolchain that
only needs minor tweeks for all NetBSD ports.

My concern is with what happens before this stage is reached (when doing
a new port or importing an updated tool).  Compare the process:

	o	take GNU application

	o	certify

	o	apply local fixes
		and submit testcases
		(and fixes) to GNU

with what is more typical of the current reality (and not just NetBSD):

	o	take GNU toolchain

	o	re-do base port to NetBSD

	o	certify

	o	apply local fixes

	o	throw results away
