Stub-out the ppi_* functions in ppi.c with empty wrappers that simply

return an error code when building on MacOS X.  This commit makes
AVRDUDE compile and run fine on my PowerMac G5 running MacOS X.  In
theory it would be possible to support parallel ports on the Mac using
a PCI multi-port card and/or USB<->Parallel converters.  If/when such
support is added we can flesh out these functions as needed, but for
now, only serial port programmers are currently supported.

Note that I tested avrdude on the G5/MacOS X with an STK500 programmer
and used a Keyspan model USA-19HS USB<->RS232 adapter device which
simply shows up in /dev as a POSIX serial port.  None of the serial
port handling needed any changes.
