String to float uses the Eisel-Lemire algorithm for better performance
in most cases, however this requires a very large table. Some
configurations, such as embedded devices, don't care about speed as much
as code size. This patch adds a flag to disable the Eisel-Lemire
algorithm as well as other code size savings for string to float.
