See the section in OE-Core's layer.conf:

"""
# Avoid adding bison-native to the sysroot without a specific
# dependency in the recipe. This means indirect dependencies
# (e.g. X -> Y -> binutils-cross -> bison-native) no longer meet the
# dependency incidentally. This improves determinism and avoids build
# failures when people switch to external toolchains.
# libarchive only needs e2fsprogs headers at buildtime
SSTATE_EXCLUDEDEPS_SYSROOT += "\
    .*->autoconf-native \
    .*->automake-native \
    .*->bison-native \
"""

If we add m4-native to that list, it would do that. Just need someone
to work through all the failures it might generate.

Cheers,
