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.

elf2flt is specifically for cases where an MMU is not available.
There is no point in building elf2flt when using an MMU.
