+#   export DEJAGNU_SIM_LINK_FLAGS="-Wl,--dynamic-linker=/local/home/sellcey/nightly/install-mips-mti-linux-gnu/sysroot-mips-mti-linux-gnu/usr/lib/ld-2.17.90.so -Wl,-rpath=/local/home/sellcey/nightly/install-mips-mti-linux-gnu/sysroot-mips-mti-linux-gnu/usr/lib:/local/home/sellcey/nightly/install-mips-mti-linux-gnu/mips-mti-linux-gnu/lib"
+#   make check RUNTESTFLAGS="--target_board=generic-sim"
+#
+# With multi-sim.exp I can skip the export and just do:
+#   make check RUNTESTFLAGS="--target_board=multi-sim"
+#
+# And I can also do this now:
+#   make check RUNTESTFLAGS="--target_board=multi-sim\{-EB,-EL\}\{-mhard-float,-msoft-float\}"
