as your target is an ARM processor you need a ARM cross-compilation
toolchain.

you can download such a toolchain from several places, a popular one
is http://www.codesourcery.com/sgpp/lite/arm. you could also build one
yourself using a framework like crosstool-ng
(http://ymorin.is-a-geek.org/dokuwiki/projects/crosstool), though this
is an advanced option.
have a look at http://elinux.org/Toolchains for a fairly complete list

if there is already a linux system running on your target system i
recommend you to start with the toolchain supplied by the board
vendor. otherwise it is very likely that your binary will not execute
on your target.

if you can afford it i recommend you the purchase of one of the
following books:

Building Embedded Linux Systems (ISBN 978-0596529680)
Embedded Linux Primer (ISBN 978-0131679849)

the embedded linux wiki at http://elinux.org is also a good starting
point

happy hacking!
