Add configuration test script (#1091).

A configuration test script has been added that allows testing of the configuration after an install. This configuration test script can be used by a continous integration system to check the validity of the configuration script.
Exclude testconf.sh
In case of error, exit with 1.
Test script runs in bash shell to guarantee correct output redirection on all systems.
Change back to /bin/sh shell and use different redirection syntax.

Add missing hyphens in configuration script.
Handle special case that $manpath is undefined.

The code

  MANPATH="$man_dir:$(manpath)"

led to problems on opensolaris systems, as $manpath is not defined there. The following code works

  manpath=${manpath:-}
  MANPATH="$man_dir:${manpath}"

The first line sets an empty default value. Note also that the () brackets have been replaced by curly brackets.
