    kexec-tools-klibc: Deliberately add -O2
    
    This helps the compiler to be more aggressive and do the expected
    optimizations to remove unused code which otherwise gets flagged on some
    architectures e.g. armv7l
    
    errors like
    undefined reference to `bad_unaligned_access_length'
