Set the DEJAGNU environment variable to point to a "site.exp" file that 
changes the flags.

For arm-elf with ARM code I use

case "$target_triplet" in {
    { "arm*-*-netbsd*" } {
      set board_info(unix,gcc,no_trampolines) "true"
      set board_info(unix,objc,no_trampolines) "true"
      set board_info(unix,g77,no_trampolines) "true"
    }
    { "arm*-*-elf*" } {
      set target_list { "arm-sim" }
    }
}

And for Thumb code I use

case "$target_triplet" in {
    { "arm*-*-netbsd*" } {
      set board_info(unix,gcc,no_trampolines) "true"
      set board_info(unix,objc,no_trampolines) "true"
      set board_info(unix,g77,no_trampolines) "true"
    }
    { "arm*-*-elf*" } {
      set target_list { "arm-sim/-mthumb" }
    }
}

I believe it's possible to have more than one entry in the target list, in 
which case all the combinations will be run, but I've never tried it.
