WARNING: I would *not* recommend the following, because while I'm an advanced *NIX user, I can't possibly comprehend the breadth of all manner of things related to compiling and programming, and GCC is an unwieldy beast.
With that warning said, I will simply say, that compiling the 32-bit GCC worked for *me*, by doing the following:
1) Create a local directory where you will install the new GCC.
# mkdir /usr/local/gcc/32
2) Always, always, always build GCC in a *separate* directory. Do *not* build GCC in it's own tree! Repeat, again and again and again, do *not* build GCC in its own tree. If it fails, your tree will be forever contaminated, and you will *never* be able to build in that tree again. *Never*! You'll have to 'make clean', and then delete the GCC directory, and start all over.
# cd /tmp
# tar xjf gcc-<version>.tar.bz2
# mkdir gcc-<version>-obj
# cd gcc-<version>-obj
3) Copy over kernel headers and system libraries to your new local directory:
