tools/autoconf: clean up build recipes

The configure option datarootdir
defaults to PREFIX/share.

The Host/Clean define should be Host/Uninstall
otherwise it is removing the build directory
before there is a chance to try "make uninstall"
in that directory.
Host/Clean/Default is no longer defined.

Use default build recipes defined in host-build.mk
instead of custom ones that are equivalent.
