I started with the arm-sim.exp file and modified it to make it work
for aarch64. The libgloss.exp patch is to make a big-endian
aarch64_be-elf target work. I just submitted a gdb simulator patch
for big-endian support.
With this dejagnu support, running the gcc C language testsuite for an
aarch64-elf build, I get
=== gcc Summary ===
# of expected passes 35433
# of unexpected failures 254
# of unsupported tests 131
which is pretty good.
