Explicit targets are:
configure -- configure the build area ready for a build.
libraries -- build the support library.
kernel -- build the kernel.
taskLibraries -- build all the support libraries for the tasks.
tasks -- build all the tasks.
The default target is to compile everything and to do a final link.
Compilation can only be undertaken after a configuration.
