We have the same issue in strace's ptest Makefile as we did with apr:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/3822

which leads to:

https://valkyrie.yocto.io/pub/repro-fail/oe-reproducible-20260413-8huodsh5/packages/diff-html/

CC_FOR_BUILD = gcc  -std=gnu23 

vs

CC_FOR_BUILD = gcc

so we probably need a similar sed fix there?

Cheers,
