Subject: kernel-arch: fall back to GNU ld unless ld-is-lld is in DISTRO_FEATURES
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=f92bfb5309d87aaf5f9683cd3e80e2a1884db6dc;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

kernel-arch: fall back to GNU ld unless ld-is-lld is in DISTRO_FEATURES

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.
