GDB 17 build failure with musl

Hi GDB,

I've just updated crosstool-ng to include gdb 17.1 and the aarch64
musl toolchain fails with

[ERROR]    /home/runner/work/crosstool-ng/crosstool-ng/.build/aarch64-unknown-linux-musl/src/gdb/gdbserver/../gdb/arch/aarch64-gcs-linux.h:35:8:

Does this ring any bells for anyone? Builds with gdb 16.3 are fine.

Thanks,
Chris
