Your 'make touch' workaround does not work for packages that contain some
*.m4 files, an aclocal.m4 file, a configure file, and a config.h.in file.

What we would need is a command that shifts the time stamps of all files
in a directory. It could be called as
  shift-mtime --offset=TIME_OFFSET DIRECTORY...
e.g.
  shift-mtime --offset=-42m foobar-0.5
