842c390469 x86-64: Treat R_X86_64_PLT32 as R_X86_64_PC32 
Starting from binutils commit bd7ab16b4537788ad53521c45469a1bdae84ad4a:

https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=bd7ab16b4537788ad53521c45469a1bdae84ad4a

x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
32-bit PC-relative branches.  Grub2 should treat R_X86_64_PLT32 as
R_X86_64_PC32.

2a5a532c00 Support grub-emu on x32 (ILP32 but with x86-64 instruction set) 
* configure.ac: Remove -m64 from checks for -mcmodel=large and
-mno-red-zone.  These are always either unnecessary (x86_64-emu) or
already in TARGET_CFLAGS at this point, and they produce incorrect
results when building for x32.
* grub-core/kern/x86_64/dl.c (grub_arch_dl_relocate_symbols): Cast
pointers to Elf64_Xword via grub_addr_t, in order to work on x32.
* include/grub/x86_64/types.h (GRUB_TARGET_SIZEOF_VOID_P,
GRUB_TARGET_SIZEOF_LONG): Define to 4 on x32.

8c534b85f1 Revamp relocation handling. 
Move more code to common dl.c. Add missing veneers for arm and arm64.
	Decreases kernel size by 70 bytes on i386-pc (40-50 compressed)
