At present buildman allows you to specify the directory containing the toolchain, but not the actual toolchain prefix. If there are multiple toolchains in a single directory, this can be inconvenient.
Add a new 'toolchain-prefix' setting to the settings file, which allows the full prefix (or path to the C compiler) to be specified.
Update the documentation to match.
