As Thomas said, it does not work. But, some unofficial hacks exist:
* remove build/.root will force to reinstall skeleton
* remove build/*/.stamp_target_installed force reinstall each target package
* depending of you toolchain, you can reinstall libc and co by removing
# stamps/ext-toolchain-installed (external)
# stamps/ct-ng-toolchain-installed (ctng)
# target/lib/libc.so.0 (buildroot)
Remind, there are ton of reasons these tips could do wrong things. The only
current official way to rebuild target is "make clean".
