    Fix #5289 (loading libstdc++.so in GHCi), and also fix some other
    linking scenarios.  We weren't searching for .a archives to satisfy
    -lfoo options on the GHCi command line, for example.
    
    I've tidied up the code in this module so that dealing with -l options
    on the command line is consistent with the handling of extra-libraries
    for packages.
    
    While I was here I moved some stuff out of Linker.hs that didn't seem
    to belong here: dataConInfoPtrToName (now in new module DebuggerUtils)
    and lessUnsafeCoerce (now in DynamicLoading, next to its only use)
