This enables modular printf LLVM libc implementation that for now can leave floating point support out, if it is not used, see https://discourse.llvm.org/t/rfc-printf-code-size-optimization/83146/35 This gives a clear benefit in code size: a trivial printf a float number sample is 37K of code while similar printf an integer is only 13K.
