Thank you for giving us a details of this problem. But can we fix this
problem with .ORDER statements? Putting ".ORDER: obj all" or alike to
Makefile doesn't fix to me (maybe I misunderstand the usage of .ORDER
statement)...

What should we do if we want to check the existence of a directory and
kick one (not two or more) command after chdir to that directory? Much
Makefiles in our FreeBSD repository employ "cd ${dir} && command" to
do this... Should we say
if [ -d ${dir} ]; then \
(cd ${dir}; command) \
else
false
fi
or exist() directive of make(1) ?
***
Anyway, attached below is current sample patch to fix this problem.
"make obj" and "make all" are separated to two individual commands
(redundant 'cd' clause, but it should work).
