Fix several "defined but not used" warnings with gcc-5

GCC 5 is able to prove that in some translation units the static Logger
instance is defined but never used, and generates an unused variable
warning for each one of them. These warnings become fatal errors when
building in debug mode, due to -Werror.

Silence the compiler by not declaring the unused variables.
