[Lazarus] Gdb and openocd via lazarus

[Michael Ring]

TUI is a rather seldomly used option, I also saw that some linux distros 
do not support it. If you want it you will perhaps really need to build 
a version of gdb for yourself.

Your openocd file looks fine on first glance, I would propably not do 
the flash command manually and instead use gdb's command to do the 
flashing, but in the end the result should be pretty much the same. 
Using gdb for flashing is perhaps a little better because you do not 
need to change your openocd config file when you binary file changes. If 
I find the time tonight I will see if this works, but I will not promise 
anything ;-)

So what is your status right now, can you already single step through 
your code and does entering
break main
cont

work ?
