Is that all? Are you sure?

Autoconf has a legacy-mode where you can specify a platform (used for 
both build and target, I don't know really what that would be useful for 
other maybe if the configure autodetection fails), without giving any 
--option prefix, e.g.
sh configure my-platform
instead of
sh configure --build my-platform --target my-platform

This feature has been deprecated for a long time, but does not seem like 
it's going away. However it prints this warning.

So my guess is that you are sending in some additional piece of command 
line arguments. If you also specify target setting using 
--openjdk-target or --build/--target/--host, these will override, and 
you can send in "badgerbadgerbadger" for all it's worth, and the only 
result would be the above warning.
