1c4dc293df 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.

ieee1275_fb is not built on sparc64 due to virtual address issues.

255b9e0bea grub-module-verifier: Add mips to all_video whitelist.
On MIPS video is compiled-in. So all_video is empty. Whitelist it.

6371e9c104 grub-module-verifier: Ignore all_video emptiness on xen.
It's intentional that it's empty when no video modules
are available.

dcc499aaf0 module-verifier: allow limited-range relocations on sparc64.
clang as incomplete mcmodel=large support. As we don't currently need full
mcmodel=large support for sparc64, relax those checks.

e1b2b9bf1d module-verifier: Check range-limited relative relocations.
Check that they point to the same module, so will end up in the same
