Binary for gdb.exe in toolchain

[hreintke]

The toolchain download for windows version 1.20.0-26-gb404fb9-2
http://arduino.esp8266.com/win32-xtensa-lx106-elf-gb404fb9-2.tar.gz

Does not contain the xtensa-lx106-elf-gdb.exe

Is there a location where I can download the gdb.exe binary ?

@igrr may we update the tool chain to this?

As far as i can tell, there is an issue with gdb in esp-alt-sdk: DimmKirr/esp-alt-sdk#23. Once it is resolved, we can switch to these toolchain builds.

@igrr it has been over a year and a half, and the referenced issue is still open in the other repo. Do we still want to use that repo? What alternatives are there?
BTW, I'd love to move to a newer toolchain, if at all possible.

I think we can try moving at least to gcc 5.2.0. I have CI environment set up for it here, so we don't need esp-alt-sdk repo linked above to build the tools.
