Pass on the argument value of the magic --gdb arg to gdb. Useful to

start pike in gdb and run it right away with pike --gdb=r ...

Rev: bin/pike.in:1.9

bin/pike.in

 #!/bin/sh
 # Runs Pike directly from the build directory.
+#
+# If the first argument is --gdb, Pike will be loaded inside a gdb
+# session with the remaining arguments. If --gdb has a value, e.g.
+# --gdb=run, the value will be passed as a command to be executed
+# initially by gdb.
