Looking at the flymake source code, this still seems to be the case in
Emacs 28.

It seems like this should be pretty easy to fix -- if we extend
`flymake-proc--init-find-buildfile-dir' to take a list of build file
names instead of a single file and then perhaps add a user option to
allow specifying the makefile names and use that in
`flymake-proc-simple-make-init' (etc.)?  (And have "Makefile" as the
first entry in that user option to preserve backwards compatibility.)

João, does that sound like a likely solution?
