lib: add weak clz/ctz functions
Some architectures need __c[lt]z[sd]i2() for __builtin_c[lt]z[ll] and that causes a build failure. They can be implemented using the fls()/__ffs() and overridden by linking arch-specific versions may not be implemented yet. This is required by "lib: add lz4 compressor module".
