Don Cross c86445ccce Mac fix: eliminate 'realpath' from makedoc script. ...

The program 'realpath' does not come installed on Mac OS.
This caused the bash script 'makedoc' to fail on Mac.
The only place I used realpath was to convert relative
paths to absolute paths for filenames passed to
check_internal_links.py.

It turns out Python has a standard function os.path.realpath()
that does the same thing, so I moved the logic into the
Python script itself. Thus makedoc no longer needs the
realpath program, and the Python function will work on
all platforms.

There is a general lesson here: in the future I will
consider moving more of my scripting logic into Python.
It has proven to be more portable than a mixture
of bash scripts and Windows batch files.
