85 + This selects the instruction set architecture of your Ubicom32 CPU. This
86 + information is used for optimizing purposes. To build a library that
87 + will run on any Ubicom32 CPU, you can specify "v3" here.
88 + If you pick anything other than "v3," there is no
89 + guarantee that uClibc will even run on anything other than the
90 + selected processor type.
91 +
92 + You should probably select the Ubicom32 ISA that best matches the
93 + CPU you will be using on your device. uClibc will be tuned
94 + for that architecture.
