Quoting Andreas Schwab <schwab@suse.de>:
If you want a different name just specify it explicitly via
--build/--host/--target. There is nothing wrong with putting the
release in the canonical name.
Completely off-topic but the word "canonical" is used in American
software literature and I have never worked out what they think it
means.
According to Chambers English Dictionary:
"canonical adj
1 according to, of the nature of or included in a canon.
2 regular.
3 orthodox or accepted.
4 ecclesiastical."
None of which looks likely in the context it is used in.
