 Thank you, that works.  It also works to specify the file at invocation:
     $ arm-none-elf-gdb my-arm-executable
     (gdb) target sim
     (gdb) load
     (gdb) run
 
 For documention, I suggest mentioning also that [apparently]
     ./configure --target=arm-none-elf
 must be used in order for "target sim" to work.  The string "-none-elf"
 appears nowhere in gdb.info or "./configure --help", and it took
 a couple hours of frustrating trial-and-error (with the above SIGSEGVs)
 to figure out that --target=arm-foo-linux would not work for simulation.
 Only a web search eventually produced the magic --target=arm-none-elf.
