This patch simply takes a first step to use the NULL ISA build for tests that do not make use of a CPU. Most of the Ruby tests could go the same way, but to avoid duplicating a lot of compilation targets that will have to wait until Ruby is built as a library and linked in independently. --HG-- rename : tests/quick/se/50.memtest/ref/alpha/linux/memtest/config.ini => tests/quick/se/50.memtest/ref/null/none/memtest/config.ini rename : tests/quick/se/50.memtest/ref/alpha/linux/memtest/simerr => tests/quick/se/50.memtest/ref/null/none/memtest/simerr rename : tests/quick/se/50.memtest/ref/alpha/linux/memtest/simout => tests/quick/se/50.memtest/ref/null/none/memtest/simout rename : tests/quick/se/50.memtest/ref/alpha/linux/memtest/stats.txt => tests/quick/se/50.memtest/ref/null/none/memtest/stats.txt rename : tests/quick/se/70.tgen/ref/arm/linux/tgen-simple-dram/simerr => tests/quick/se/70.tgen/ref/null/none/tgen-simple-dram/simerr rename : tests/quick/se/70.tgen/ref/arm/linux/tgen-simple-dram/simout => tests/quick/se/70.tgen/ref/null/none/tgen-simple-dram/simout rename : tests/quick/se/70.tgen/ref/arm/linux/tgen-simple-dram/stats.txt => tests/quick/se/70.tgen/ref/null/none/tgen-simple-dram/stats.txt rename : tests/quick/se/70.tgen/ref/arm/linux/tgen-simple-mem/simerr => tests/quick/se/70.tgen/ref/null/none/tgen-simple-mem/simerr rename : tests/quick/se/70.tgen/ref/arm/linux/tgen-simple-mem/simout => tests/quick/se/70.tgen/ref/null/none/tgen-simple-mem/simout rename : tests/quick/se/70.tgen/ref/arm/linux/tgen-simple-mem/stats.txt => tests/quick/se/70.tgen/ref/null/none/tgen-simple-mem/stats.txt
