UNW_REMOTE_ONLY fixes

Browse source 
Exclude <link.h> because it is only required for local unwinding when
iterating over the program headers.

Have the following DWARF related functions available in case of
UNW_REMOTE_ONLY because they are used by libunwind-ptrace:
  dwarf_find_debug_frame
  locate_debug_info
  find_binary_for_address
  load_debug_frame
  debug_frame_tab_new
  debug_frame_tab_append
  debug_frame_tab_shrink
  debug_frame_tab_compare
