#5647: CLI option to silence "Loading package foo ... linking ... done" output

---------------------------------+------------------------------------------
When building libraries with GHC that require compile-time evaluations,
such as TemplateHaskell, the per-compilation unit progress output, i.e.
{{{
[ n of N] Compiling Foo.Bar.Doo ( ... )
}}}
is flooded with several
{{{
Loading package foo ... linking ... done.
}}}
lines for each library required by the interpreted compile-time code.
Although this information is definitely useful for tracking down compile-
time linking issues, its a bit too verbose IMHO.
I couldn't find any CLI option, to selectively disable just those linker
messages, but keep the compilation progress output, therefore I'd hereby
request the feature to provide a CLI option to disable outputting just
those `Loading package ...` message while keeping everything else as is.
