Set -Wno-unused-but-set-variable globally
As of gcc-4.6 the option -Wunused-but-set-variable is enabled by default. While this is a useful warning there are numerous places in the ZFS code when a variable is set and then only checked in an ASSERT(). To avoid having to update every instance of this in the code we now set -Wno-unused-but-set-variable to suppress the warning. Additionally, when building with --enable-debug and -Werror set these warning also become fatal. We can reevaluate the suppression of these error at a later time if it becomes an issue. For now we are basically just reverting to the previous gcc behavior.
