'true' is internal shell function, so only shell is called. If full path=20
will be specified as /usr/bin/true, make calls it directly without shell.
/usr/bin/true is much smaller but still one process will be created.

Another variant is to create suffix rule for all such cases (using some=20
intermediate pseudo-suffix) and specify .if defined() there only once.
