This does not seem like the right place to me to adjust the settings. I
think (not sure; never tried it) that the right technique is in the
nativesdk-meson recipe:

    install -d ${D}${SDKPATHNATIVE}/post-relocate-setup.d
    install -m 0755 ${WORKDIR}/meson-setup.py
${D}${SDKPATHNATIVE}/post-relocate-setup.d/

    # We need to wrap the real meson with a thin env setup wrapper.
    mv ${D}${bindir}/meson ${D}${bindir}/meson.real
    install -m 0755 ${WORKDIR}/meson-wrapper ${D}${bindir}/meson
