    PR10678 vta-gcc: module debuginfo: relocation refers to undefined symbol
    
    libdwfl tries to resolve all relocations in a module debuginfo file and
    if it cannot find a symbol used in a relocation it will fail when
    dwfl_module_getdwarf() is called. So we must make sure all possible
    dependencies of the module are also in the dwfl. We do this by trying
    to find and parse the modules.dep file and insert all dependencies
    into the dwfl.
    
    * setupdwfl.cxx (elfutils_kernel_path): Lift from setup_dwfl_kernel and
      make static.
      (is_comma_dash): New function.
      (modname_from_path): Likewise.
      (setup_mod_deps): Likewise.
      (setup_dwfl_report_kernel_p): Call setup_mod_deps().
    * testsuite/buildok/pr10678.stp: New test.
