buildman: Add a way to specific a full toolchain prefix

Browse Source 
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.

The toolchain-alias section indicates that the i386 toolchain should be used
to build x86 commits.
Note that you can also specific exactly toolchain prefixes if you like:
[toolchain-prefix]
arm: /opt/arm-eabi-4.6/bin/arm-eabi-
or even:
[toolchain-prefix]
arm: /opt/arm-eabi-4.6/bin/arm-eabi-gcc
This tells buildman that you want to use this exact toolchain for the arm
architecture. This will override any toolchains found by searching using the
[toolchain] settings.
Since the toolchain prefix is an explicit request, buildman will report an
error if a toolchain is not found with that prefix. The current PATH will be
searched, so it is possible to use:
[toolchain-prefix]
arm: arm-none-eabi-
and buildman will find arm-none-eabi-gcc in /usr/bin if you have it installed.
3. Make sure you have the require Python pre-requisites
