MIPS: tools: Add relocs tool This tool is based on the x86/boot/tools/relocs tool. It parses the relocations present in the vmlinux elf file, building a table of relocations that will be necessary to run the kernel from an address other than its link address. This table is inserted into the vmlinux elf, in the .data.relocs section. The table is subsequently used by the code in arch/mips/kernel/relocate.c (added later) to relocate the kernel. The tool, by default, also marks all relocation sections as 0 length. This is due to objcopy currently being unable to handle copying the relocations between 64 and 32 bit elf files as is done when building a 64 bit kernel.
