Extend the `install_prep/<component>` and `install_prep/all` targets to the Makefile generators. Some differences compared to the implementation for Ninja: * A Makefile rule name cannot contain `:`, so components whose names contain one get no preparation target. * A top-level rule cannot build an individual custom command output, so a generated file to be installed is prepared by building the target that owns its custom command. * When a target must be relinked before installation, its `preinstall` rule is built after its `all` rule. * Where the make tool matches target names case-insensitively, components whose names differ only in case share a preparation target, as done for `test_prep/`.
