Delete bin2boot. But I adamantly oppose removal of this port and bsp until x86_64 is available.

GCC is considering removal of other targets including m68k. Even with it removed, we could choose to stick with an old toolset.

I don't want to remove all pc386 BSP variants. This ticket is about the removal of bsps/i386/pc386/config/pc386.cfg. I don't want to touch the pc486 for example.

I just realized that the bin2boot is used by all i386 BSPs, see also #3410.

The post link process is badly defined and implemented inconsistently in the BSPs that supported it. I suspect it is only of use in a limited number of cases and in specific use cases for some hardware configurations. The data in the .cfg files is important and should be kept until we can find a suitable way to export the important details to all application build systems.

I do not think I have used the bin2boot method of booting a PC and current use the standard ELF file our link process generates via the iPXE boot loader that is loaded by a BIOS PXE loader. All this stuff is widely available, clearly documented and supported.
