Faster RISC OS build service builds

This recording compares the RISC OS native runs of AMU to the host runs of AMU in RISC OS build service.

By default, all the commands you run in the build service run through the RISC OS environment - as you might expect. However, it is possible to use the host system to perform builds instead. Instead of using amu to build things, we can use hostamu, which takes the same Makefile, but runs it on the host system. This makes things much faster. In this case, reducing the build of the PrinterBuffer module (a C module that implements the configuration of the printer buffer) from 26.6 seconds on the build service to 5.6 seconds - most of which was the data transfer and start up of the environment.

The riscos-build-run tool is a simple script that wraps the riscos-build-online command to make it easier to run things.
