Subject: [PATCH v3 1/3] kernel-arch: fall back to GNU ld unless ld-is-lld is in DISTRO_FEATURES
Date: Mon, 20 Jul 2026 18:31:17 +0900	[thread overview]
Message-ID: <20260720093119.3245892-2-mark.yang@lge.com> (raw)
In-Reply-To: <20260720093119.3245892-1-mark.yang@lge.com>

From: "mark.yang" <mark.yang@lge.com>

Nothing stages a bare ld.lld unless ld-is-lld is in DISTRO_FEATURES,
so a clang kernel fails its first linker check on any other setup.
Use GNU ld.bfd from binutils-cross instead.

Signed-off-by: mark.yang <mark.yang@lge.com>
---
v3: no changes
v2: new patch; the merged clang support uses a bare ld.lld which
    nothing stages without ld-is-lld
