Not the best approach in my opinion.

You may always use sniprintf(), which does _NOT_ support any floating
point formats, but it also does _NOT_ use malloc(). Generally in newlib
there are non-floating-point variants of all printf- and scanf-like
functions - just add the "i" right before printf/scanf and you are
done. For example there is iprintf, siprintf, sniprintf, viprintf and
so on.
