Description: GCC-14 compatibility patch

* Disable FCF protection on i386, where it's not supported. 
* Add missing include to resolve implicit printf() function declaration.
* Add missing header file for long jumps in efi/main.c, fix invocations.
* Type-cast addr_t pointer to size_t, assumes that their size is the same.
