[PATCH] gdb: sim: automatically pass down sysroot

- Subject: [PATCH] gdb: sim: automatically pass down sysroot
Since gdb sets up a nice sysroot path for us by default, automatically
pass it down to the sim target so it too gets a good default. This does
not override anything the user explicitly specifies of course.

* remote-sim.c (gdbsim_open): Add the strlen of " --sysroot=" and
gdb_sysroot to the "len" variable. Append both to "arg_buf".
