#264 sdcc --help goes to stderr and not stdout

[Peter Dons Tychsen]

Hello SDCC team,

Normally a command like "cc --help | less" is a good way to get an overview. However, SDCC puts the text in the wrong stream.

Like GCC and other it should put the text in STDERR when it hits an error, and put the text in STDOUT when a command completes OK.

The following patch makes "sdcc --help | less" and "sdcc --h | less" work as expected.

Thanks,

/pedro
