[gdal-dev] No SONAME in libgdal.so when building with --without-libtool

[Even Rouault]

Gareth,

What sort of issue do you encounter with SONAME not being defined ?

I've tested your patch and it doesn't generate the same soname as libtool.  
libtool generates libgdal.so.20 deduced from the LIBGDAL_CURRENT / 
LIBGDAL_REVISION / LIBGDAL_AGE variables.

Digging into history, it seems to be a voluntary choice not to define by 
default the soname in non-libtool builds, but I'm not sure why :
