It's not usually relevant, but these days recommended practice is
setting the variables *after* ./configure, e.g.:
./configure LDFLAGS=-L/opt/... \
--prefix=... --enable-32-bit --build=...

At least w/ gcc, can you just add -m32 to your compiler command line?
./configure CFLAGS="-m32" LDFLAGS=-L/opt/... \
--prefix=... --enable-32-bit --build=...
