elfutils: upgrade 0.179 -> 0.180
Drop all the debian patches: they are very invasive, the use case is unclear, and rebasing them is just too hard. Refresh 0002-musl-libs.patch Add a new musl fix: 0015-config-eu.am-do-not-use-Werror.patch Add a reproducibility fix: 0001-tests-Makefile.am-compile-test_nlist-with-standard-C.patch (From OE-Core rev: 79c290a0823ee996c69bb02a82dc6ded00fae629) Signed-off-by: Alexander Kanavin <alex.kanavin@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

4Subject: [PATCH] config/eu.am: do not use -Werror
5
6Due to re-definition of error() on musl, gcc starts throwing
7errors where none happen with glibc. Since upstream is not
8likely to be interested in musl builds, lets just disable
9Werror.

4Subject: [PATCH 1/3] Ignore differences between mips machine identifiers
5
6Little endian binaries actually use EM_MIPS so you can't tell the endianness
7from the elf machine id. Also, the EM_MIPS_RS3_LE machine is dead anyway (the
8kernel will not load binaries containing it).

4Subject: [PATCH 3/3] Add mips n64 relocation format hack
5
6MIPSEL N64 ELF files use a slightly different format for storing relocation
7entries which is incompatible with the normal R_SYM / R_INFO macros.
8To workaround this, we rearrange the bytes in the relocation's r_info field
9when reading and writing the relocations.
10
11This patch also ensures that strip.c sets the correct value of e_machine
12before manipulating relocations so that these changes take effect.
