    tools/elfutils: add more pkg-config library info
    
    In order for linking the static libraries from elfutils to work,
    other libraries need to be included to handle the references
    to functions made in the library's objects that are not included
    as they would already be if the library was a shared object instead.
    
    A shared object library stores this list of libraries when it was made,
    so that the dynamic linker can refer to that list at runtime,
    but a static library has no such functionality so the list of libraries
    for missing functions must be included at link time.
    
    This information was already added to the pc file for libelf
    using the definitions in src/Makefile.am,
    so extend this to the rest of the pc files in the project.
    
    For situations where the libraries may be used
    without pkg-config setting the flags and library list,
    this patch and the pc files can serve as a quick reference.
