kbuild, LLVMLinux: Add -Werror to cc-option to support clang
Clang will warn about unknown warnings but will not return false
unless -Werror is set. GCC will return false if an unknown
warning is passed.
Adding -Werror make both compiler behave the same.
[arnd: it turns out we need the same patch for testing whether -ffunction-sections
works right with gcc. I've build tested extensively with this patch
applied, so let's just merge this one now.]
