I'm using Debian packages. So, shouldn't this be the goal of the Debian
packages? Also, I don't see how this can be handled with several GCC versions
installed, as each GCC version has its own liblto_plugin.so.

If one compiles with "-flto", then everything should be automatic to use the
right plugin as needed, without needing the end user to specify other
"configure" environment variables.
