After a quick inspection, I noticed the issue does not happen if `MEMSET_OPTSPEED` is selected.

Doing bisect I discovered that the issue was caused by commit ee931c137fb795630b4c68f040861583d52a3efd
Adding -fno-builtin back to CFLAGS fixed the issue:
```
diff --git a/boards/sim/sim/sim/scripts/Make.defs b/boards/sim/sim/sim/scripts/Make.defs
index fb6bad3a97..abaa5bb2bd 100644
