Which version of GNU as (binutils) are you trying to use?  I had serious
problems with 2.12.1 generating invalid O32 (same as IRIX 5) object files,
while 2.13 seems to be mostly ok.  In the cases I investigated, the IRIX ld
(6.2 and 6.5 O32, not 5.3) correctly errored out on those files.

Besides, unless you have installed the resulting as in
/usr/local/gcc-3.2/gcc-lib/mips-sgi-irix5.3/3.2/as, you need to point
configure at the as path with --with-as=<path to as>.

And finally, are you really running IRIX 5.3 or merely trying to get an O32
gcc on IRIX 6?  In the latter case, you may want to have a look at the
mainline, which already includes most of my patches to produce an
mips-sgi-irix6*o32 configuration.
