MIPS: add dynamic relocation support
The code handles relocation entries with the following relocation types only: mips32: R_MIPS_REL32 mips64: R_MIPS_REL+R_MIPS_64 xburst: R_MIPS_REL32 Other relocation entries are skipped without processing. The code must be extended if other relocation types must be supported. Add -pie to LDFLAGS_FINAL to generate the .rel.dyn fixup table, which will be applied to the relocated image before transferring control to it. The CONFIG_NEEDS_MANUAL_RELOC is not needed after the patch, so remove that as well. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
