-Fix unresolved external "fiprintf".
-When newlib is configured with:
-
-  --enable-newlib-nano-formatted-io
-
-"fiprintf" should be an alias of "fprintf". However the alias does 
-not seem to work properly, as we encounter unresolved external
-error if we uses "assert" in code. So we patch the code directly.
