Support for std::{from,to}_chars isn't finalized in
libcxx as of the time of writing, see __cpp_lib_to_chars in
https://github.com/llvm/llvm-project/blob/6331bfa41ab529558ec9d645c0effb7a4146591c/libcxx/docs/FeatureTestMacroTable.rst
This patch adds a fallback using strtof. There are two
differences:
* strtof is locale-dependent
* strtof tolerates leading spaces
