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.

Enable selecting elf2flt for RISC-V 64-bits no MMU builds and add
support for it in the form of an additional patch (upstream pull request
https://github.com/uclinux-dev/elf2flt/pull/22).
Also modify the package Makefile.in file to add the -fPIC option to
the target CFLAGS for RISC-V 64-bits no MMU builds.
This patch is based on initial work by Christoph Hellwig <hch@lst.de>.

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

elf2flt contains a program called ld-elf2flt, which gets installed as
a replacement for ld, with ld renamed to ld.real. This program
therefore calls ld.real internally.
The logic to find ld.real worked fine for:
- bin/TARGET_ALIAS-ld
- TARGET_ALIAS/bin/ld
However, it failed badly if bin/SIMPLER_TARGET_ALIAS-ld is used, as
symlink to bin/TARGET_ALIAS-ld. For example:
$ ./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 adding a patch that adjusts the ld-elf2flt
logic to properly cope with this situation.

The uClinux developers now have a Github with elf2flt code, with an
upstream that is again active. Let's switch to this upstream, which
has built-in support for ARM noMMU, contributed by Waldemar.
Since we're now fetching from github, a hash file is added as well.
Finally, we disable -Werror to avoid build issues caused by warnings.
