- update to 20200825 (bsc#1142609, CVE-2019-14249)
  libdwarf now reads .debug_gnu_pubtypes & pubnames
  (non-standard but gcc creates them in DWARF5)
  via a small number of new functions
  and dwarfdump  --print-debug-gnu prints both sections.
  Verifying the .debug_info offsets is not yet done.
  Dwarfdump now dumps DWARF5 .debug_rnglists and
  .debug_loclists.  To handle DWARF5 there are
  a small number of new functions. All existing
  functions are still supported, but
  to read DWARF5 some small changes are required.
  In libdwarf see libdwarf2.1.pdf and also see
  dwarfdump now takes much less malloc() to work, as measured
  by valgrind --tool=massif  and massif-visualizer.
  A dwarfdump run that did 2.2Gib of malloc/free before the changes
  now does 1.4GiB.
  libdwarf and dwarfdump now support DWARF5 .debug_rnglists.
  The new interfaces are documented in libdwarf/libdwarf2.1.pdf.
  The new option to dwarfdump is "--print-raw-rnglists".
  The code (dwarfdump/libdwarf), regressiontests,
  and readelfobj directories and all their tests
  are known to work on Linux(Ubuntu on x86_64 and i686), 
  FreeBSD, MacOS Catalina (with Apple Command Line Tools),
  and IBM s390 (Big Endian!) running Ubuntu Linux.
  On Windows-MinGW the full regression tests
  have not been tested, but 'make check' works
  for dwarfdump/libdwarf (the current dwarfdump 
  make check actually does run dwarfdump and 
  checks that dwarfdump basically works).
  Now a --disable-libelf configure/build of libdwarf/dwarfdump
