An alternative to a cross compiler is to just use distributed compilation and set the current box to 0 so all jobs get distributed to other faster x86 boxes. In the past I regularly used this to build arm on a x86 and more fun building for OSX ppc on x86. ./configure and basic make stuff occur on the "slow" arm/ppc, but the actual build jobs are sent out to the farm for building.
