Hans-Christian Noren Egtvedt 803f9b84f6 packages/gdb: add gdb-11.2
Forward port patches from gdb-11.1, as they still apply clean, hence
still assumed to be relevant.

Subject: [PATCH 2/2] xtensa: make sure ar_base is initialized
ar_base is uninitialized for cores w/o windowed registers as their
regmap doesn't have register 0x0100.
Check that ar_base is initialized and if not initialize it with a0_base.
gdb/
* xtensa-tdep.c (xtensa_derive_tdep): Make sure ar_base is
initialized.
