I just tried to test the version bump of iproute2 to v5.11 and I see
the same/similar error on utils/pkg-test for
bootlin-armv5-uclibcbootlin-armv5-uclibc.

Looks like your patch in uclibc [1] is not in the used version of the
bootlin toolchain [2]. As far as I can see the toolchain uses uclibc
v1.0.34.

[1] https://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/?id=8bc41f131b8d70c84c300f14cd64abd448126b43
[2] https://toolchains.bootlin.com/releases_armv5-eabi.html

I think we have to wait until the toolchains will be updated to
include uclibc version 1.0.36 or greater.

Thank you
