But libXaw.so.<major_number> is the default behaviour for libtool.  Are you
using -release instead of -version-info or -version-number? I think
-version-number will give you exactly what you need.

========
`-version-number MAJOR[:MINOR[:REVISION]]'
     If OUTPUT-FILE is a libtool library, compute interface version
     information so that the resulting library uses the specified
     major, minor and revision numbers.  This is designed to permit
     libtool to be used with existing projects where identical version
     numbers are already used across operating systems.  New projects
     should use the `-version-info' flag instead.
========

May be you're explicitly passing libXaw6.la as the library name instead of
libXaw.la. You should pass libXaw.la as the library name instead of
libXaw6.la or libXaw7.la. Let me give an example:

========
$ touch xaw.c
$ libtool  --mode=link gcc -rpath /usr/lib -version-number 6:0:0 -o libXaw.la 
xaw.c
rm -fr  .libs/libXaw.a .libs/libXaw.la .libs/libXaw.lai .libs/libXaw.so 
.libs/libXaw.so.6 .libs/libXaw.so.6.0.1
gcc -shared    -Wl,-soname -Wl,libXaw.so.6 -o .libs/libXaw.so.6.0.0
(cd .libs && rm -f libXaw.so.6 && ln -s libXaw.so.6.0.0 libXaw.so.6)
(cd .libs && rm -f libXaw.so && ln -s libXaw.so.6.0.0 libXaw.so)
ar cru .libs/libXaw.a 
ranlib .libs/libXaw.a
creating libXaw.la
(cd .libs && rm -f libXaw.la && ln -s ../libXaw.la libXaw.la)
$ libtool  --mode=link gcc -rpath /usr/lib -version-number 7:0:1 -o libXaw.la 
xaw.c
rm -fr  .libs/libXaw.a .libs/libXaw.la .libs/libXaw.lai .libs/libXaw.so 
.libs/libXaw.so.6 .libs/libXaw.so.6.0.0
gcc -shared    -Wl,-soname -Wl,libXaw.so.7 -o .libs/libXaw.so.7.0.1
(cd .libs && rm -f libXaw.so.7 && ln -s libXaw.so.7.0.1 libXaw.so.7)
(cd .libs && rm -f libXaw.so && ln -s libXaw.so.7.0.1 libXaw.so)
ar cru .libs/libXaw.a 
ranlib .libs/libXaw.a
creating libXaw.la
(cd .libs && rm -f libXaw.la && ln -s ../libXaw.la libXaw.la)
========

As you can see, The SONAME is libXaw.so.6 or libXaw.so.7 which is exactly
what you want. By the way, I have libtool 1.5.6 on Debian.
