Yep. I was mistaken initially. The task that failed for me is the do_make_icudata.

Within that task, the last command fails:

do_make_icudata:class-target () {
    ${@bb.utils.contains('PACKAGECONFIG', 'make-icudata', '', 'exit 0', d)}
    [...]
    install -Dm644 ${S}/data/out/icudt${ICU_MAJOR_VER}l.dat ${S}/data/in/icudt${ICU_MAJOR_VER}l.dat
}

We do not see it with poky, because PACKAGECONFIG does not contain make-icudata.
We have the following in a bbappend of our distro layer:

FILESEXTRAPATHS:prepend := "${THISDIR}/files:"
SRC_URI += "file://filter.json"
PACKAGECONFIG += "make-icudata"
PACKAGECONFIG:pn-icu-native += " make-icudata"

which triggers the error.
