Fix conditional setting of build tools variables in the makefile

As pointed out by Tormod Volden, make automatically sets CC and AR. Instead
of a conditional setting of those variables, automatically add BUILDTPREFIX
to them if it is set without overriding the values of CC, AR, and RANLIB.
Also have extra default conditional settings of those three variables in the
event that they happen not to be set for some reason.
