query ghc for the linkerflags for -staticlib?

Hi, when building a library with -staticlib, how can we query ghc to tell us the linker flags, that would be needed to link the produced library. (e.g. -liconv and -lgmp)? I tried --print-ld-linker-flags and --print-gcc-linker-flags and found they were broken, as is specified in #9614. Also --info does not provide the needed information. Cheers, Moritz
