Use correct compiler version flag in the autoconf script

The autoconf script prints used compiler version at the end of the
configure script.  Solaris native compiler doesn't support --version,
and -V has to be used which in turn isn't supported by Gcc/Clang.
Detect which version flag has to be used and call $CC with it.
