efivar-38: ld.lld: error: unknown argument '--add-needed'

[telans]

The new release fails to build with ld.lld due to --add-needed. This option has been deprecated from GNU ld in favour of --copy-dt-needed-entries (ld (1)), but that still isn't supported by lld.

[telans]

Do you mind elaborating as to why --add-needed is required? It seems like a rarely used option that might work well as a drop-in for --as-needed?

[telans]

I can't reproduce this with clang-14, closing.

[tmaakis]

Well it does do that for me on clang 14.

[thrifty-txt]

This issue persists with clang and LLD 14. Should be re-opened.
