[oe] How to rebuild images with updated PREFERRED_PROVIDER_xxx in machine conf?

[Jiason Li]

Sorry all,

My step was:
1. bitbake some-image, oe/openembedded/recipes/some-pkg.bb was bitbaked.
2. bitbake -c clean some-pkg
3. update machine conf with PREFERRED_PROVIDER_some-pkg = "some-pkg-mine"
4. bitbake some-pkg, according to the log,
oe/overlay/recipes/some-pkg-mine/some-pkg-mine.bb was bitbaked
correctly.
5. bitbake some-image, but some-pkg was still bitbaked and was in
some-image, not some-pkg-mine!
6. rm -rf oe/overlay/tmp
7. bitbake some-image, this time some-pkg-mine is in some-image, finally.

Any info are very appreciated. :)

Thank you!
