Simply unconditionally uncompress any section to make sure indexes between
sections check out. Add some testcases with various compressed sections.

GCC6 -Wduplicated-cond found the following issue:
elflint.c: In function ‘compare_hash_gnu_hash’:
elflint.c:2483:34: error: duplicated ‘if’ condition [-Werror=duplicated-cond]
else if (hash_shdr->sh_entsize == sizeof (Elf64_Word))
~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
elflint.c:2448:29: note: previously used here
if (hash_shdr->sh_entsize == sizeof (Elf32_Word))
~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
Which is correct, a Word in both Elf32 and Elf64 files is 4 bytes.
We meant to check for sizeof (Elf64_Xword) which is 8 bytes.
Also fix the section index and name in the error message.
The reason we probably didn't see this issue before is that SHT_HASH
sections really always should have sh_entsize of 4 even on 64bit arches.
There are however a couple of arches with mistakes in their sysv ABI.
See libelf/common.h. This also would only be triggered if on such an
architectures when the ELF file would have both a SHT_HASH and SHT_GNU_HASH
section and elflint would try to compare those sections.
Add an example testfile-s390x-hash-both to run-elflint-test.sh.

The parallel-tests option was introduced in automake 1.11 and is the
default since automake 1.13. All tests can now be ran in parallel with
make check -j. To enable this all tests are ran in their own temporary
directory so they don't stomp on each others input or output files.
On my machine (4 cores) make check takes ~20 seconds, but now with
make check -j8 takes only ~4 seconds.
ChangeLog:
* configure.ac (AM_INIT_AUTOMAKE): Request parallel-tests.
tests/ChangeLog:
* Makefile.am (installed_TESTS_ENVIRONMENT): Export environment,
remove wrapper.
(TESTS_ENVIRONMENT): Likewise.
(installed_LOG_COMPILER): New variable defining wrapper.
(LOG_COMPILER): Likewise.
* run-*.sh: Fixup location of input and output files.
* test-subr.sh: Create test_dir, pushd to execute test in.
(trap): Remove test_dir.
(testfiles): Use abs_srcdir.
(installed_testrun): Match on abs_builddir or abs_top_builddir.
(self_test_files): Adjust path.

readelf -d doesn't work if a SHT_NOBITS section is right before the actual
.dynamic section at the same offset. elflint also fails on such binaries.
So skip SHT_NOBITS sections at the same offset in [g]elf[32|64]_offscn().
