    perf dwarf-aux: Fix build with !HAVE_DWARF_GETLOCATIONS_SUPPORT · 008979cc
    James Clark authored
    The linked fixes commit added an #include "dwarf-aux.h" to disasm.h
    which gets picked up in a lot of places. Without
    HAVE_DWARF_GETLOCATIONS_SUPPORT the stubs return an errno, so include
    errno.h to fix the following build error:
    
      In file included from util/disasm.h:8,
                     from util/annotate.h:16,
                     from builtin-top.c:23:
      util/dwarf-aux.h: In function 'die_get_var_range':
      util/dwarf-aux.h:183:10: error: 'ENOTSUP' undeclared (first use in this function)
        183 |  return -ENOTSUP;
            |          ^~~~~~~
    
    Fixes: 782959ac ("perf annotate: Add "update_insn_state" callback function to handle arch specific instruction tracking")
