It doesn't work even in the cases where upstream's Makefile.am uses
-avoid-version.  Libtool is still adding a -Wl,-soname:

address@hidden:~/src/jabberd2-jas/storage$ /bin/bash ../libtool  --tag=CC   
--mode=link gcc -I../c2s -I.. -g -O2 -funsigned-char -module -avoid-version  -o 
authreg_anon.la -rpath /usr/local/lib/jabberd authreg_anon.lo -lexpat -L../util 
-lssl -lcrypto -lgsasl -ludns -lidn -lexpat -lresolv -lcrypt  -ldl -lz
libtool: link: rm -fr  .libs/authreg_anon.la .libs/authreg_anon.lai 
.libs/authreg_anon.so
libtool: link: gcc -shared  -fPIC -DPIC  .libs/authreg_anon.o   -L../util -lssl 
-lcrypto /usr/lib/libgsasl.so -ludns -lidn 
/usr/lib/x86_64-linux-gnu/libexpat.so -lresolv -lcrypt -ldl -lz  -O2   
-Wl,-soname -Wl,authreg_anon.so -o .libs/authreg_anon.so
libtool: link: ( cd ".libs" && rm -f "authreg_anon.la" && ln -s 
"../authreg_anon.la" "authreg_anon.la" )
address@hidden:~/src/jabberd2-jas/storage$ 

Is this intentional, or should we start to track down how -Wl,-soname
was added and treat that as a bug?  The manual says:

'-avoid-version'
     Tries to avoid versioning (*note Versioning::) for libraries and
     modules, i.e. no version information is stored and no symbolic
     links are created.  If the platform requires versioning, this
     option has no effect.

I don't know whether libtool regards the debian/gnu/linux/elf platform
as requiring versioning or not.

This is libtool 2.4.2 from Debian, if it matters.
