This is a handy one-liner for seeing what defines gcc has:
	echo | powerpc-linux-gcc -E -dM -
When I run it with a cross-compiled gcc 2.95.3 *and* 3.2, I see both
	#define __linux__ 1
	#define __powerpc__ 1
The 2.95.3 was compiled with exactly the directions you refer to above.
3.2 was slightly different, but in both cases --target=powerpc-linux .
