[wrynose][PATCH 13/20] binutils: inherit upstream-stable-release-point

[<daniel.turull@ericsson.com>]

From: Daniel Turull <daniel.turull@ericsson.com>

binutils cuts a per-X.Y stable branch, binutils-2_46-branch for the
current series, that takes only bugfixes and backported CVE fixes, and
tags X.Y.Z (Z>0) releases from it. Superseded branches stay alive: one x86
MODRM fix landed on the 2.40, 2.42 and 2.43 branches on the same day in
May 2025. So upgrades within a major.minor are stable point upgrades per
the OE-Core stable release policy (ref-manual, "Stable Point Release
Upgrades"). This is not spelled out in a policy document, so qualification
rests on the branch structure and the release contents below.

  https://sourceware.org/git/?p=binutils-gdb.git;a=shortlog;h=refs/heads/binutils-2_46-branch

Checked the last two point releases. 2.46.1 (Jun 08 2026) is 137 commits,
mostly automatic version-string date bumps, with six substantive changes,
all fixes: gprof testsuite, build warnings, an sframe encoder/decoder
call-site fix, a DOS-filesystem fix and two linker fixes. 2.45.1 (Nov 10
2025) is aarch64/gas fixes to incorrectly restricted instruction
encodings, linker metadata fixes adding GLIBC_ABI_*_TLS version
dependencies to match glibc's own ABI tags, and libctf, strip and warning
fixes. Neither adds options or instruction support.

Already tracked this way on the OE stable branches, counting only bumps
since each branch forked: kirkstone has five or more "binutils: stable
2.38 branch update(s)" commits staying within 2.38.x, scarthgap the same
for 2.42.x, and wrynose has already taken 2.46.1.
