Externals/glslang: Silent even more warnings 

* -Wno-unused-but-set-variable: only set this flag with gcc, otherwise
  clang will issue warnings about the warning option being unknown :)
  (-Wunknown-warning-option)

* -Wmissing-variable-declarations: clang warns about missing extern
  declarations for non-static variables.
