[PATCH] gdb: sim: handle target sysroot prefix

The default gdb sysroot now sets itself to "target:". This works for
most remote targets, but when using the simulator, this causes problems
as the sim will attempt to search for that path.
Update the remote-sim logic to skip this leading prefix when it is found
so that the sysroot isn't passed in as an invalid value.

* remote-sim.c: Include gdb_bfd.h.
(gdbsim_open): Declare new local sysroot pointing to gdb_sysroot.
Skip TARGET_SYSROOT_PREFIX in gdb_sysroot when it is set.
