Hi Aaron,
Funny, I had no idea this existed. But it is actually used by readelf
(for showing the program interpreter) and there is one test case (that
does the same).

Looks nice. Just two small questions below.
DEFAULT_INCLUDES includes -I. which is needed for compiling the
testcases with -DMAIN_CHECK=1.
This fixes make check after commit 76bd5f6bea9b "config: Adjust
AM_CPPFLAGS for srcdir and .. path includes"
* libdw/Makefile.am (CHECK_DEF_FLAGS): Add DEFAULT_INCLUDES.
Signed-of
ed header files.
* config/eu.am (AM_CPPFLAGS): Use -iquote for $(srcdir) and
replace -I.. with -I$(abs_top_builddir).
* libdw/libdwP.h: Include "libdw.h" and "dwarf.h" instead of
the system headers and .
https://sourceware.org/bugzilla/show_bu
(validate_strdata): New
function taking Elf_Data and restricting d_size to last zero
char.
(translate_offs): Call validate_strdata.
(find_symtab): Likewise for both symstrdata and aux_symstrdata.

Debian stable only has valgrind 3.19.0 which doesn't have an openat2
syscall wrapper. This makes some elfutils tests fail under valgrind
since it uses openat2 explicitly now. So switch the build factory to
not use valgrind, but the gcc address (and undefined) sanitizer.
