elf/elf.h: Add new 386 and X86_64 relocations from binutils.
The following new 386 and X86_64 were added to binutils. They are non-dynamic relocations, so don't need direct handling in glibc. But other programs, like elfutils, use the glibc elf.h definitions for the names and numbers when inspecting ET_REL files. R_386_GOT32X was proposed in https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX were proposed in https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0 There also used to be R_X86_64_PC32_BND and R_X86_64_PLT32_BND but those already got deprecated in https://groups.google.com/d/msg/x86-64-abi/-hdQyMixt8Y/XFDOvioG85cJ * elf/elf.h (R_386_GOT32X): New. (R_386_NUM): Update. (R_X86_64_GOTPCRELX: New. (R_X86_64_REX_GOTPCRELX): New. (R_X86_64_NUM): Update.
