Mark Charlebois 045812536e kbuild, LLVMLinux: Add -Werror to cc-option to support clang
commit c3f0d0bc5b upstream.

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.]
