Did you miss the previous reply which mentioned using '-B/usr/lib32 
-B/usr/local/lib32' in addition to '-m32'?  From gcc(1):
The run-time support file 'libgcc.a' is also searched for using the '-B' 
prefix, if needed.  If it is not found there, the two standard prefixes 
above are tried, and that is all.  The file is left out of the link if 
it is not found by those means.  Most of the time, on most machines, 
'libgcc.a' is not actually necessary.
