Subject: [PATCH] chore: add mold linker config for aarch64-unknown-linux-gnu
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes ARM64 Docker build failure caused by R_AARCH64_CALL26 relocation
overflow when linking libv8. mold automatically generates range
extension thunks (veneers) to bridge calls exceeding the ±128MB limit.
