Part of the automake VI patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

> 5) rtems-rc-19990202-1.diff/reorg-install.sh
>
> reorg-install.sh fixes a Makefile variable name clash of RTEMS
> configuration files and automake/autoconf standards.
> Until now, RTEMS used $(INSTALL) for install-if-change. Automake and
> autoconf use $(INSTALL) for a bsd-compatible install. As
> install-if-change and bsd-install are not compatible, I renamed all
> references to install-if-changed to $(INSTALL_CHANGED) and used
> $(INSTALL) for bsd-install (==automake/autoconf standard).  When
> automake will be introduced install-if-change will probably be replaced
> by $(INSTALL) and therefore will slowly vanish. For the moment, this
> patch fixes a very nasty problem which prevents adding any automake file
> until now (There are still more).
