a problem, maybe not a bug

hi,
I use the postgresql package for my embeded platform. while
cross-compile the package, It occurs an error and I can't dispose it.
Maybe your can give me some advise.
My configure file (as follows):

############
#!/bin/bash

rm config.cache config.status -f

CC=arm-linux-gcc \
CXX=arm-linux-g++ \
./configure --prefix=/usr/local/armlinux/arm-linux \
--build=i386-linux \
--host=arm-unknown-linux \
--without-readline

after configure, I use "make" command to compile the package, and
everything is ok. So
I use "make install" to install the package. An error occurs(as follows).

Entering directory `/home/acvolcano/mx21/mgis/postgresql-8.0.4/src/port'
make[3]: Nothing to be done for `all'.
make[3]: Leaving directory
`/home/acvolcano/mx21/mgis/postgresql-8.0.4/src/port'
./zic -d /usr/local/armlinux/arm-linux/share/postgresql/timezone

./zic: ./zic: cannot execute binary file
make[2]: *** [install] Error 126
make[2]: Leaving directory

make[1]: *** [install] Error 2
make[1]: Leaving directory `/home/acvolcano/mx21/mgis/postgresql-8.0.4/src'
make: *** [install] Error 2

Obviously, the error is usage of the binary file zic, which only can
execute in arm processor.
How can I correct the configure file? I just know a little about the
autoconf.
