Add the Clang specific -Wmissing-variable-declarations to WARNS=6.
This compiler flag enforces that that people either mark variables static or use an external declarations for the variable, similar to how -Wmissing-prototypes works for functions. Due to the fact that Yacc/Lex generate code that cannot trivially be changed to not warn because of this (lots of yy* variables), add a NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this specific compiler warning.
