[ACTIVITY] Report for week #13

Hello,

[GNU-796] Stabilize GDB testsuite results in the CI

- Committed ABE change suggested by Maxim to mention failures that cause additional testsuite runs.

- Tried to update Python MinGW build to 3.x, but it's a rabbit hole. Proposing to disable Python support when cross-building GDB with MinGW instead.

- First regression detected by the tcwg_gnu_native_check_gdb CI job reported upstream¹. Started investigating it.

[GNU-767] Support changing SVE vector length in remote debugging

- Created a testcase to exercise the corner case mentioned by Pedro. Found out that GDB is also susceptible to it. Fixed both GDB and gdbserver. Posted patch series upstream².
