Linking against the static Swift SDK libraries has never been implemented for dynamic library products

[finagolfin]

Description

@ephemer reported that this wasn't working with my Android SDK bundle a couple months ago, finagolfin/swift-android-sdk#194, and I see this flag has only ever applied to executables since Ankit first implemented it 7.5 years ago.

Has there ever been any discussion of applying it to dynamic libraries also? The workaround in my linked issue gets it to build, though I haven't tested the resulting library to see if it has any runtime issues.

Pinging @spevans, @jakepetroules, @MaxDesiatov, and @kabiroberai, as you all touched some of the surrounding code in subsequent commits.

Expected behavior

Linking dynamic libraries with --static-swift-stdlib works just like for executables

Actual behavior

I get this linker error from the build steps below, because that repo has a dynamic library product but -static-stdlib isn't passed to the Swift compiler:
