Comment 1 Marco Scardovi (scardracs) 2021-03-07 14:09:16 UTC
I'm building this on Gentoo. If I set LANG="en_US" then it works without any problem
Comment 2 Marco Scardovi (scardracs) 2021-03-07 14:23:52 UTC
Just to be clear:

if x86_64-pc-linux-gnu-ld --version is ld GNU it will works
if x86_64-pc-linux-gnu-ld --version is ld di GNU it will not works
Comment 3 Alfred Wingate 2021-03-07 14:29:46 UTC
I'd add to the issue that the issue is caused by (binutils) ld with localization like Italian (the one above is Italian), Finnish and Gaelic which differ from the English "GNU ld" output in `x86_64-pc-linux-gnu-ld --version`.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/ld-version.sh?h=v5.12-rc2#n38

```
if [ "$1" = GNU -a "$2" = ld ]; then
	shift $(($# - 1))
	version=$1
	min_version=$bfd_min_version
	name=BFD
	disp_name="GNU ld"
elif [ "$1" = GNU -a "$2" = gold ]; then
	echo "gold linker is not supported as it is not capable of linking the kernel proper." >&2
	exit 1
elif [ "$1" = LLD ]; then
	version=$2
	min_version=$lld_min_version
	name=LLD
	disp_name=LLD
else
	echo "$orig_args: unknown linker" >&2
	exit 1
fi
```

Which leads to this code to fail on output like
```
ld di GNU (Gentoo 2.35.2 p1) 2.35.2
Copyright (C) 2020 Free Software Foundation, Inc.
Questo programma è software libero; siete liberi di ridistribuirlo secondo i termini

but not 
```

```

This issue didnt come up because the linker checking code was like this:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/scripts/Kconfig.include?h=v5.11.4#n42
```
# Fail if the linker is gold as it's not capable of linking the kernel proper
$(error-if,$(success, $(LD) -v | grep -q gold), gold linker '$(LD)' not supported)

```

The commit that changed the linker checking behavior:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/scripts/ld-version.sh?h=v5.12-rc2&id=02aff85922043cf175ebbe5fc3430acfeaeb8393
Comment 4 Nicolas Werner 2021-03-07 14:30:40 UTC
Specifically the problem here is that 02aff85922043cf175ebbe5fc3430acfeaeb8393 changed the linker matching logic from checking for not being "gold" to it having to include "GNU ld". This does not work on all locales (most notably Finnish, Gaelic and Italien, I think), so the linker is marked as unsupported. The check should probably set the C locale or don't check for the string "GNU ld" at least.
