Simplify replacement code for strtof.
strtof() is in C99 and all targeted systems have it. We can remove theconfigure probe and some dead code, but we still need replacement codefor a couple of systems that have known buggy implementations selectedvia platform template.Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us>Discussion:https://postgr.es/m/152683.1659830125%40sss.pgh.pa.us
