version bump elfutils 174 -> 176

and take over patches from debian. It is needed to make MIPS work.

+Subject: [PATCH 1/3] Ignore differences between mips machine identifiers
+
+Little endian binaries actually use EM_MIPS so you can't tell the endianness
+from the elf machine id. Also, the EM_MIPS_RS3_LE machine is dead anyway (the
+kernel will not load binaries containing it).

+Subject: [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.
