[PATCH] x86: Fix broken multiboot2 buliding for i386

[Kairui Song]

When building for i386, an error occured:

kexec/arch/i386/kexec-x86.c:39:22: error: 'multiboot2_x86_probe'
undeclared here (not in a function); did you mean 'multiboot_x86_probe'?
39 |  { "multiboot2-x86", multiboot2_x86_probe, multiboot2_x86_load,
   |                      ^~~~~~~~~~~~~~~~~~~~
   |                      multiboot_x86_probe

kexec/arch/i386/kexec-x86.c:39:44: error: 'multiboot2_x86_load'
undeclared here (not in a function); did you mean 'multiboot_x86_load'?

   |                                            multiboot_x86_load
kexec/arch/i386/kexec-x86.c:40:4: error: 'multiboot2_x86_usage'
 undeclared here (not in a function); did you mean 'multiboot_x86_usage'?
40 |    multiboot2_x86_usage },
   |    ^~~~~~~~~~~~~~~~~~~~
   |    multiboot_x86_usage

Fix this issue by putting the definition in the right header, also tidy
up Makefile.
