The configuration of newline endings for stdout and stdin is supported only by the VFS drivers. The write and read syscalls in newlib automatically convert LF to CRLF for stdout and CR to LF for stdin, ignoring the configured newline settings. Therefore, make the options for newline endings visible only when VFS is enabled. Signed-off-by: Frantisek Hrbata <frantisek.hrbata@espressif.com>
