[PATCH 3/3] Add mips n64 relocation format hack

MIPSEL N64 ELF files use a slightly different format for storing relocation
entries which is incompatible with the normal R_SYM / R_INFO macros.
To workaround this, we rearrange the bytes in the relocation's r_info field
when reading and writing the relocations.

This patch also ensures that strip.c sets the correct value of e_machine
before manipulating relocations so that these changes take effect.
