[PATCH v2 2/2] gdb: Split python's version into major/minor and check for embed option

[Frank Kühndel]

Hi Chris,

again I tested your two new patches with SPARC/RTEMS 6 on the following OS:

* openSUSE Leap 15.3 Python 2.7.18
* Ubuntu 22.04 LTS Python 3.10.4
* AlmaLinux 8.5 (Arctic Sphynx) Python 3.6.8
* Debian GNU/Linux 11 (bullseye) Python 3.9.2
* Fedora Linux 35 (Container Image) Python 3.10.4

Everything worked fine.

Many thanks for your efforts
