[Buildroot] [PATCH] package/docker-credential-gcr: needs NPTL

[yann.morin]

From: "Yann E. MORIN" <yann.morin@orange.com>

docker-credential-gcr calls pthread_getattr_np() which is only available
with NPTL; i.e. always available with glibc (where it originates from,
since 2.2.3), always available with musl (which has had it since 0.9.10
in 2013), and only available when uClibc has NPTL (since 1.0.0 in 2015).

Fixes: https://autobuild.buildroot.org/results/3ed18da254082b7823b49be4578274792bb7380e/

Thomas, Thomas, All,

This should also be backported to 2026.02, to fix the following build
failure:
    https://autobuild.buildroot.org/results/aa5754a547f6dea3165e598f8e22b6cbe3b38f5b/

Similarly, the following commits, related to the other docker credential
helpers, should also be backported :

    882c35f7388a  package/docker-credential-acr-env: needs NPTL
    7a7b0522b34c  package/amazon-ecr-credential-helper: needs NPTL

Either that, or the 2026.02 branch should no longer be built in the
autobuilder is it is no longer maintained...

Regards,
Yann E. MORIN.

Indeed, 2026.02.x is now EOL. I fixed the autobuilder config earlier
this week:

commit e1d90c57b65a2b37db8f4aaa0ce3068f1db957b7 (HEAD -> master, origin/master, origin/HEAD)
Author: Peter Korsgaard <peter@korsgaard.com>
Date:   Tue Aug 18 23:37:45 2026 +0200

    web/branches: test next instead of 2026.02.x

    Now that 2026.02.x is EOL.
