As of Tiger I don't think you are supposed to use gcc 3.3 to build
anything else apart from the MacOSX kernel, and as I recall that
is only for PowerPC.

As far as building OKL4 is concerned, the only version which supports the 
native compilers included in XCode is the Iguana from the Darbat project.  
The Darbat project is quite old, it is based on the ERTOS Iguana 1.1
release.  The present version has some of the infrastructure support there, but 
some things are missing.  For one thing it does not have the machine 
target which tells it to build for Mach-O format and with a proper compiler
toolchain (gcc/Mach-O rather than GNU).

The other option to build it on a Mac is to use an ELF cross
toolchain.  (built with something like crosstool).  This
should let you build up to to the part with the OKL4 bootimage.
The grub in the build system does not work on anything other than
x86/Linux so you will need to copy the image.elf to an existing
grub installation.
