-Wall is a meta-option that turns on a large number of option.
You may want all -Wall options except -Wone-ring. It is logical
to have -Wno-one-ring, so you can do '-Wall -Wno-one-ring'. It
is completely illogical to do "-Wall -Wno-all" on a command line.
Your project CLFAGS example make no sense. The project
would need to handle that one special file has an exception
with or without -Wno-all, so you end up with a custom build
(e.g. Makefile target).
The correct fix is to globally reject -Wno-all.
