Should be rm -f to avoid error if the stamp file doesn't exist.
$(STAMP_DIR)/ct-ng-toolchain-installed should also be removed.
$(GCC_BUILD_DIR3)/.installed should also be removed, if an internal
toolchain is used.
Staging dir should probably also be removed, else it doesn't work correctly when
you remove a library (configure script would detect it as still being present
and would link against it). But of course, removing a library is anyway problematic
(as David pointed out) because the executables that have been compiled against
it will not be recompiled. If staging dir is removed, it's possible that
some more stamp files will have to be removed as well, too.
I'm a bit afraid that this change is risky, in the sense that it is easy to
forget to remove some stamp files. OTOH, I think it's a very useful feature.
So there are three ways we can deal with that:
- Be very strict and not support this feature.
- Include the feature and deal with the issues that are reported on the list
when they occur.
- Include the feature and add a test for it in the autobuilders. E.g., after
generating a rootfs, save it, do a target-clean, recreate the rootfs, and
compare.
