It seems that gdb doesn't build for xtensa since a while, indeed commit
[1] merged in gdb 9 introduced a few number of build issues on several
architectures:

[Fix gdb build on macOS]
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=b1c896b365f2dbcd14145a88d103623244cf0fb0

[gdb: Fix gdb build on mips64-linux]
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=2208ee917050bcc901c7faefdee257ffbf8ef2ab

[gdb: Fix native build on Linux/Alpha.]
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=7a27b85f6d9b5eea9bd1493f903158fbea4b2231

[Include gdbarch.h in m68k-linux-nat.c]
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=a7cdaa914f4b937544d8f102679bb5129bb1ef08

[gdb: include gdbarch.h in hppa-linux-nat.c]
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=ad75efa628656716982f2674008952bfd2c268af

Most of them has been fixed before the gdb 9 release but it seems
that xtensa is the last one on this list and still unfixed with
gdb 11 (not even noticed by Buildroot autobuilders).

gcc 12 is also broken due to too old xtensa overlay for gdb:

xtensa overlays form 2016 override gdb/xtensa-config.c breaking
the gdb 12 build due a recent changes from commit:
