revisiting this, I noticed an error in my reproducer script (the --prefix
option should have been --prefix=/usr), but since I'd had some success with
that machine, spent some time to determine the cause of the problem.
Basically, the problem is that make -j is chopping up the list in
a line like this:
install: $(INSTALL_DIRS) $(INSTALL_FILES)
and executing the rules for the latter first. I suppose that I can
add a configure check for ".WAIT" and use that:
install: $(INSTALL_DIRS) .WAIT $(INSTALL_FILES)
