Unfortunately I do not know very much about how GCC defines its target
platform.  I stumbled through it once to produce that win32 config file.

One approach is to download the source to GCC 4.2 and try configuring it
under MSys or cross-compiled from a linux machine for the desired target
platform.  Then look in the resulting files to see what options it used.

Sorry I cannot be of more help.  I'm on another deadline right now.
