Subject[PATCH] kbuild: clang: Disable -Wunused-const-variable warnings
Date
Disable -Wunused-const-variable warnings instead of
disabling -Wunused-variable warnings, So that in both
clang and GCC -Wunused-const-variable gets disabled.

Currently with clang -Wunused-variable warnings are
disabled and with gcc -Wunused-variable warnings are
enabled, with this setting all unused local variable
would be warned in clang as well.
