# HG changeset patch # User "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr> # Date 1293643180 -3600 # Node ID f55ffa24e6be5a7f23f7794d9fbfcb77d8d07570 # Parent fff72415427a478c782c588878fd67d34028b7f3 binutils/binutils: add wrapper to gold and ld When both gold and ld are installed, add a wrapper that calls to either gold or ld. In case the wrapper is installed, we also need to symlink ld.bfd and ld.gold for the core_cc steps. Signed-off-by: "Yann E.
