meson.eclass: Pass -Db_lto=false globally Pass `-Db_lto=false` globally to force-disable appending `-flto` in projects that default to it. In Gentoo, users enable LTO via setting `*FLAGS` manually. If a package really needs to pass `-Db_lto=true` because the build system enables some custom logic based on it, `tc-is-lto` can be used to determine whether LTO is enabled, and then `-Db_lto=true` can be passed explicitly by the ebuild.
