98 * Config has a global notion of which machine type is
99 * being used. It uses the name of the machine in choosing
100 * files and directories. Thus if the name of the machine is ``i386'',
101 * it will build from ``Makefile.i386'' and use ``../i386/inline''
102 * in the makerules, etc. machinearch is the global notion of the
103 * MACHINE_ARCH for this MACHINE.
109 * For each machine, a set of CPU's may be specified as supported.
