Creation of freeldr diskette with the new building system

[Gge]

I don't know how to create a freeldr diskette with the new building 
system  .

freeldr.sys is created in output-i386/boot/ftreeldr but the boot sector 
needs to be created .

The previous method "install a: fat" from boot/freeldr/install directory 
  does not work anymore )

Any idea ?
