libosmo-sccp: Build breakage on --disable-static

Hi,

I just looked into a build breakage when --disable-static is passed. The first failure is because of:

libosmo_sigtran_la_LDFLAGS = -version-info $(LIBVERSION) \ -no-undefined \ -export-symbols-regex '^osmo_'

The testcases use xua_* sua_ symbols but they are not exported. Shall we export them or shall we forbid --disable-static on libosmo-sccp?

The second part is that I had preferred the sccp library to be static only to avoid having to do proper ABI checking/versioning. If we fix the above, maybe we have to fix this part too?
