lkr042: reduced code size with smart-io:

The objective of this test is to verify that a
mixed I/O call application built with -msmart-io=1
uses less memory than a mixed call application
built with --no-smartio=0.

Note: Compiler option -msmart-io=1 is the default
setting. The option is used explicitly in this test.

How to execute the test:

1. Set the environment variable $PIC30_CD
    to your pic30 tools binary directory
2. Export $PIC30_CD
3. Edit the Configuration section of file "go"
4. Execute "go"

To get verbose output:

Execute "go -v"
