In my experience, that leads to the same problem as if the targets are
are part of of the same rule. One common workaround for this problem
is to introduce a "stamp" file to serialize the build, like this.
rumpdefs.h rumpvnode_if.h rumpvnode_if.c: rump-stamp
bmake's .NOTPARALLEL would probably work too, at the expense of
serializing the entire directory.
I've never used .WAIT, but the from the manpage it appears to be
used for serializing dependencies rather than build targets.
