[PATCH] toolchain/classes: Add lld-native dependency when using lld as system linker

[Khem Raj]

This was not an issue before lld split from clang, but now its an independent
recipe and needs to be brought into dependency chain, otherwise clang fails to
build with -flto as it does not find gold or lld plugins.

Conditional python in a very core variable like this isn’t ideal, and the clang-cross recipe already has this dependency. Is that not sufficient, or  is there some edge case where that dependency isn’t enough?

Yeah I am also troubled by this. It shows up when enabling LTO since gold
linker is gone clang would work with LLD but it does not find it in rootfs
I will dig recipe that shows it but generally I think clang expects lld
when lto is enabled. Cross clang would pull it into its own build but not
into systoots its building packages in somehow
