MIPS: Use Makefile.postlink to insert relocations into vmlinux
When relocatable support for MIPS was merged, there was no support for an architecture to add a postlink step for vmlinux. This meant that only invoking a target within the boot directory, such as uImage, caused the relocations to be inserted into vmlinux. Building just the vmlinux target would result in a relocatable kernel with no relocation information present. Commit fbe6e37dab97 ("kbuild: add arch specific post-link Makefile") recified this situation, so MIPS can now define a postlink step to add relocation information into vmlinux, and remove the additional steps tacked onto boot targets.
