Fix build and errno check on musl libc (#1678)

In the 'from_chars' function, it's first checked if errno != 0 and
immediately returns with std::errc::result_out_of_range aka ERANGE.
Please refer issue [1624] (#1624)

The function 'strtol_l' is not available on non GLIBC systems hence on
other libc use the alternative 'strtol' function.
