package/elf2flt: update to version 2021.08

Browse Source 
It contains several fixes and improvements compared to our current
version, and two of our patches have been accepted upstream. Most
notably, it fixes the issue we had in using elf2flt with recent
versions of binutils (upstream commit
ba379d08bb78c9300e84351c11080c26ddcc36b3).

Patch 0001-ld-elf2flt-behave-properly-when-called-with-a-name-d.patch
is upstream as of commit 1c9b454336eaf38f7d037917a3120fae04193fbe

Patch 0002-elf2flt.c-add-new-relocation-types-for-xtensa.patch is
upstream as of commit d7eb73163bcea31168c438fc132a0967ac172e3d

The other two patches are refreshed to apply properly on 2021.08.

From b31e9b1bff6832063816b972395179859d1d4619 Mon Sep 17 00:00:00 2001
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Date: Sun, 13 Aug 2017 16:03:20 +0200
Subject: [PATCH] ld-elf2flt: behave properly when called with a name different
from TARGET_ALIAS
ld-elf2flt currently handles two cases:
1 It is called as the wrapper for <TARGET_ALIAS>-ld, generally
installed in the bin/ directory of a toolchain.
2 It is called as the wrapper for "ld", generally installed in the
TARGET_ALIAS/bin/ directory of a toolchain.
Unfortunately, if for some reason it gets called using a FOOBAR-ld
name that is different from <TARGET_ALIAS>-ld, it assumes it is in
case (2), while it really is in case (1). Due to this, the path
mangling logic doesn't work, and it doesn't find ld.real.
This happens for example when the binary program in bin/ is named
arm-buildroot-uclinux-uclibcgnueabi-ld, but also has a simpler symlink
named arm-linux-ld. In this case,
arm-buildroot-uclinux-uclibcgnueabi-ld is recognized by ld-elf2flt as
containing TARGET_ALIAS, and therefore the proper logic to find
ld.real is applied. However, when arm-linux-ld is used, ld-elf2flt
doesn't find TARGET_ALIAS, and therefore assumes we're being called as
TARGET_ALIAS/bin/ld.. and searches for a program called ld.real in
bin/, which doesn't exist.
See:
$ ./output/host/bin/arm-buildroot-uclinux-uclibcgnueabi-ld
/home/thomas/buildroot/buildroot/output/host/bin/../arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: no input files
$ ./output/host/bin/arm-linux-ld
arm-linux-ld (ld-elf2flt): error trying to exec '/home/thomas/buildroot/buildroot/output/host/bin/ld.real': execvp: No such file or directory
$ ./output/host/arm-buildroot-uclinux-uclibcgnueabi/bin/ld
/home/thomas/buildroot/buildroot/output/host/arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: no input files
This commit fixes that by inverting the logic: if we're being called
as just "ld", then we assume it's the program in
TARGET_ALIAS/bin/. Otherwise, we're called through some variant of
TARGET-ld.

From d7eb73163bcea31168c438fc132a0967ac172e3d Mon Sep 17 00:00:00 2001
From: Max Filippov <jcmvbkbc@gmail.com>
Date: Thu, 7 May 2020 21:11:43 -0700
Subject: [PATCH] elf2flt.c: add new relocation types for xtensa
Xtensa have added new relocation types R_XTENSA_[NP]DIFF{8,16,32} with
the same properties as the existing types R_XTENSA_DIFF{8,16,32}.
Add them to the list of ignored relocation types.
This fixes the following error when invoking elf2flt on xtensa binaries
built with the recent binutils:
ERROR: reloc type R_XTENSA_PDIFF32 unsupported in this context
