It has to be [board_info target gdb_protocol] or [target_info
gdb_protocol].  Actually, this:

if { !([isnative] && [istarget *-linux*]) \
     && (![target_info exists gdb_protocol] \
         || [target_info gdb_protocol] != "async") } then {

Please append to GDBFLAGS instead of setting it; otherwise you'll lose
-nx and it will read $HOME/.gdbinit.

Remove the commented out lines.

Otherwise OK.  Thanks for posting this.
