[smartmontools-support] info about C++11 support

[Niclas Borlin]

Hi,

A per the request of the configure script for smartmontools-6.6, here is 
the info (I think) you wanted.

Thanks!

...
checking for g++ option to accept C++11... unknown
configure: error:
This version of smartmontools does not use C++11 features, but future
versions possibly will.
This script was unable to determine a compiler option to enable C++11.
Use option '--with-cxx11-option=OPTION' to specify the compiler option
(it will be checked, but not used in the actual build).
Use option '--without-cxx11-option' to suppress this error message if the
compiler lacks C++11 support.
In both cases, please send info about compiler and platform to
smartmontools-support at listi.jpberlin.de - Thanks!
