Basically, the decision is package dependent. But we have roughly two
types of packages :
* Packages based on the Makefile.autotools.in infrastructure. In that
case, the installation to the target space
(project_build_ARCH/PROJECT/root) is done if FOO_INSTALL_TARGET is
YES (which is the default), and if the
stamp file does not exist. See package/Makefile.autotools.in for the
* Packages *not* based on the Makefile.autotools.in. In that case, the
install is usually implement with a make target that is a file
installed in the target directory. For example, for the flex
package, it is $(TARGET_DIR)/$(FLEX_TARGET_BINARY). Therefore,
removing this file from the target directory will trigger the
re-execution of the make install of that particular package.

Theorically, removing the target directory completely + removing the
*_target_installed stamp files from
project_build_ARCH/PROJECT/autotools-stamps/ should make it. But I
don't guarantee that it will work for every package.

If they are issues in building util-linux, please don't hesitate to
report them so that we can fix them.

I gave you the tips that I have. Buildroot is definitely not good
(yet!) on cleaning up things and handling partial rebuilds. This is
definitely on my TODO-list, and I think that Peter is also very
concerned about these issues.
Hope this helps,
