Eric Wild 9a69cf3685 configure.ac: fix libtool issue with clang and sanitizer 
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"

About OsmoSGSN
==============

OsmoSGSN originated from the OpenBSC project, as a separate program within
openbsc.git. In 2017, OpenBSC was split in separate repositories, and hence
OsmoSGSN was given its own separate git repository.

OsmoSGSN exposes
- GSUP towards OsmoHLR (or a MAP proxy);
- GTP towards a GGSN (e.g. OsmoGGSN);
- Gb towards a BSS (e.g. OsmoPCU);
- IuPS towards an RNC or HNB-GW (e.g. OsmoHNBGW) for 3G data;
- The Osmocom typical telnet VTY and CTRL interfaces.
