ldtoa: don't restrict outbuf size to ndigits
https://cygwin.com/pipermail/cygwin/2021-November/249930.html
reported a regression introduce by using a dynamically sized local
char array in favor of a statically sized array.
Fix this by reverting to a statically sized array, using a small
buffer on the stack for a reasonable number of requested digits, a
big mallocated buffer otherwise. This should work for small targets
as well, given that malloc is used in printf anyway right now.
This is *still* hopefully just a temporary measure, unless somebody
actually provides a new ldtoa.
Fixes: 4d90e53359145 ("ldtoa: fix dropping too many digits from output")
