That option is a late addition to mkdir.  Some operating systems don't
accept it.  So, I put it in only the first command of the "install-dirs"
rule.  (Those system directories usually exist; so, it doesn't matter if
that line fails.)

  I suppose that I could write separate lines for each directory, and add a
shell test that won't run mkdir if the directory already exists.

That is a problem with a tradition:  It says that we should install into
"/usr/local/" when we build a package; and, we should install into "/usr/"
(or "/opt/") when the package already was built by someone else.

Uz provides three flavors of the cc65 package:
1. RPM  (RedHat Package Manager)
2. binary
3. source
He makes the pre-built RPM package install itself into "/usr/".

Whichever flavor that you choose, cc65 should install in the same way (so
that you can switch between them easily).  Therefore, I made the top-level
makefile do the same thing that "packages/rpm/redhat/cc65.spec" does.

I had fixed that bug months ago, but I forgot to send the patch to Uz!

The install program is like "mkdir -p", some operating systems don't have
it.  At the present time, I have taken the lazy programmer's way out:  I
force the user to deal with that problem.  In the makefile, at line 36, I
put:

# BSD-like install-script/-program
INSTALL    = make/install-sh
#INSTALL      = install

You are supposed to comment the "make/install-sh" line, and uncomment the
"install" line if your system has that program.
