[PATCH 2/2] build: add Uninstall for host build

[Florian Eckert]

Currently there is no possibility for host package to cleanly remove the
installed files in staging.
There is the possibility to call an uninstall make target, but if this
is not implemented, and so nothing happens.

For debugging, it makes sense to know what is being installed. With this
change, the install process is called twice.
Once to create a .host-install file and once to install the package files
into the staging directory. If the tool is removed, the .host-install file
is used to remove all files from the staging dirctories.

This only works for the generic autotools install and uninstall target.
