enable Python support in GDB

[slightlyunconventional]

The aarch64--glibc--stable gdb says:

(gdb) python
>end
Scripting in the "Python" language is not supported in this copy of GDB.

There are some pretty important tools distributed as GDB Python scripts, such as Linux's gdb scripts (including dmesg dumper), and this one-off debug a relocated executable script.

Please enable Python support in GDB. Thanks!

This change works for me:

The same config option can be enabled for the "stable" (2017.05) toolchain, but I can understand if you only want to enable new features in a future release.

Patch for toolchains-builder.git:

config: enable host-gdb's Python interpreter

There are some pretty important tools distributed as GDB Python scripts, such
as Linux's gdb scripts (including dmesg dumper).

@tpetazzoni, would you apply it?

Any chance to see this patch applied? Unfortunately, I cannot use any bootlin toolchain because I need python support in GDB.
