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).
