There is about to be a uClinux BSP release for the MCF5329/73 families that has the gcc tool set included.
Keep checking on http://www.freescale.com/webapp/sps/site/overview.jsp?nodeId=0127268688033202A9 for the release.
If just looking for gnu tools goto http://www.codesourcery.com/gnu_toolchains/coldfire/ .
They have the most recent tool chain that then gets integrated into our ColdFire BSP's.
