Some ELF link editors default to `--as-needed` and record only
those libraries in DT_NEEDED tags that are needed to resolve
undefined symbols in the shared object to be created.

In Template Haskell we rely on all symbols that were defined
in modules compiled so far to be available in the current
temporary shared object. To prevent the link editor from
dropping the DT_NEEDED tag for the previously linked temporary
shared object we need to override the link editors default and
specify `--no-as-needed` on the command line. This is for GNU ld
and GOLD ld.

This addresses #10110
