commit: https://git.buildroot.net/buildroot/commit/?id=593a60f7f0fa1489175700c7b2eda0666347faba
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
lld can be used by external packages or by setting BR2_TARGET_LDFLAGS
(though a dependency is missing to make the latter really work). Future
patches will improve the integration in the build.
