Customizing soname

[Alon Bar-Lev]

Hello,

I had an issue that I solved in patching libtool, I am not sure this was
the right thing to do, but if it was, I think it should go into libtool.

I require to produce a shared library that whose name is customizable by
the user.

I use autoconf/automake/libtool in order to build the system.

I must use libtool to create libraries, from the obvious reason of creating
proper libraries in all archs.

automake cannot get modified name as rules, so I expected something
like that work:

lib_LTLIBRARIES=m1
m1_SOURCES=xxxx
m1_LDFLAGS=$(AM_LDFLAGS) -module -avoid-version -no-undefined \
        -soname @CONFIG_SONAME@

install-exec-hook:
        mv "$(DESTDIR)$(libdir)/m1.so" "$(DESTDIR)$(libdir)/@CONFIG_SONAME@"

But I have found no way to make libtool to accept my soname. I've read most
of the script, and found no way to do it.

In the end I ended up with the attached patch, which enable the use of -soname 
argument.
This is for 1.5 series. But I've read the 2.X branch and found no solution 
there either.

As far as I undersand any other solution make the Makefile.am much more complex,
and forces me to write my own rules for building and installing my libray.

Can you please consider adding a way to specify the soname as libtool argument?

Thanks,
Alon Bar-Lev.
