[OE-core] [PATCH] meta-environment: make rpm and dnf work in toolchain

[Zheng, Ruoqin]

Hi Alex

Thank you for your advice and I have a question.

1:-> This does not seem like the right place to me to adjust the settings.

Well, did you mean that I shouldn’t adjust the settings in meta-environment recipe, instead of it, adjust the settings in the nativesdk-meson recipe?

We need to configure dnf and rpm to use and make it compatible with package architecture from yocto build system.

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
