[PATCH V4 0/1] gdb: upgrade to 17.1

[sunilkumar.dora@windriver.com]

From: Sunil Dora <sunilkumar.dora@windriver.com>

Upgrade GDB from 16.3 to 17.1.

This upgrade resolves build issues with newer toolchains and musl-based
systems. Two fixes are included to address musl compatibility and
AArch64 kernel header changes.

The previously carried Readline 8.3 alpha backport is no longer needed
and has been removed.

Changes in v4:
- Filed upstream bug for header visibility issue
- Coordinated with upstream and added workaround
- https://sourceware.org/bugzilla/show_bug.cgi?id=33926

Changes in v3:
- Fixed GDB custom baudrate issue and submitted upstream
- https://sourceware.org/pipermail/gdb-patches/2026-March/225952.html
- https://sourceware.org/bugzilla/show_bug.cgi?id=33747

Changes in v2:
- Updated patch metadata and commit title

Changes in v1:
- Initial submission upgrading GDB

Build-tested on:
- x86-64 (glibc)
- x86-64 (musl)
- aarch64 (glibc)
- aarch64 (musl)
