Hi Simon,

These targets are not really parallel; they are handled one at a time when invoked by other rules. Some recent versions of make (e.g. on MSYS2) give a warning about this. Split out the rules to avoid the warning.
I did not see any warning without this patch.
Also it looks both MSYS2 and Ubuntu 22.04 has make v4.3 which doesn't emit any warning.
