As pointed out at https://github.com/libexpat/libexpat/issues/312
libtool does not play nice with clang sanitizer builds at all. For those
builds LD shoud be set to clang too (and LDFLAGS needs the sanitizer
flags as well), because the clang compiler driver knows how linking to
the sanitizer libs works, but then at a later stage libtool fails to
actually produce the shared libraries and the build fails. This is fixed
by this patch.
Addtionally LD_LIBRARY_PATH has no effect on conftest runs during
configure time, so the rpath needs to be set to the asan library path to
ensure the configure run does not fail due to a missing asan library,
i.e.:
SANS='-fsanitize=memory -fsanitize-recover=all -shared-libsan' export
CC=clang-10 ASANPATH=$(dirname `$CC
-print-file-name=libclang_rt.asan-x86_64.so`) export
LDFLAGS="-Wl,-rpath,$ASANPATH $SANS $LDFLAGS"

We updated to 0.9.29 tag, but configure.ac was locked to 0.9.28, which
means release 0.9.29 is going to generated an old version and thus is
broken. A new release will follow this commit.

Provide a sane means of adding the -Werror compiler flag.
Currently, some of our jenkins.sh add -Werror by passing 'CFLAGS="-Werror"',
but that actually *overwrites* all the other CFLAGS we might want to have set.
Maintain these exceptions from -Werror:
a) deprecation (allow upstream to mark deprecation without breaking builds);
b) "#warning" pragmas (allow to remind ourselves of errors without breaking
builds)
As a last configure step before generating the output files, print the complete
CFLAGS and CPPFLAGS by means of AC_MSG_RESULT.

The libosmocore depedency is used for talloc and OSMO_ASSERT.
Reduce the depedencies by using libtalloc directly and replace
the ASSERT with a local one (without backtrace support).
... which in turn causes all the ASN_DEBUG() to be turned into
fprintf(stderr, ...) statements, once the user application decides
to set 'asn_debug = 1' somewhere in its code.
The next step would be to make _ASN_DECODE_FAILED / _ASN_ENCODE_FAILED
no longer depend on ASN_DEBUG (which it currently does)
