Subject: unused-variable warning is getting disabled with clang

Hi All,

When kernel compiled with clang, following line is disabling the 
unused-variable warning. This is not the case with gcc.
KBUILD_CFLAGS += $(call cc-disable-warning, unused-variable)

Are there any specific reasons for disabling unused-variable with clang?
