Thanks for explaining. But I'm still not sure I understand. What is
the difference between your test case
---------------------------------
all: foo
foo: /etc/motd
cat /etc/motd >$@
---------------------------------
and the snippet from modules/relocatable-prog
---------------------------------------
uninstall-hook: uninstall-relocwrapper
uninstall-relocwrapper:
some-statements;
---------------------------------------
and the pattern from po/Makefile.in.in:
---------------------------------
all : sanity
all : foo
sanity :
@test `expr 1 + 1` = 2
foo :
echo > foo
---------------------------------
The target has non-empty statements in each case.

An interesting idea. But in the special case of po/Makefile.in.in
I cannot use it, without making use of GNU make $(...) function call
expressions.
