Subject: tools: Remove install-if-change program

The last installed tool in RTEMS repository is the install-if-change
script.  It is not used to build/install BSPs.  This script does the
same as the standard "install" program with an additional feature to
install variants via the -V command line option.

This script is used by the standard Makefile support:

c/src/make/host.cfg.in:INSTALL_CHANGE=$(PROJECT_BIN)/install-if-change

The INSTALL_CHANGE is used by:

c/src/make/host.cfg.in:ifndef INSTALL_CHANGE
c/src/make/host.cfg.in:INSTALL_CHANGE=$(PROJECT_BIN)/install-if-change
c/src/make/host.cfg.in:INSTALL_VARIANT=$(INSTALL_CHANGE) -V
"$(LIB_VARIANT)"

Remove the support for variant installation and instead use the standard
"install" program.  This breaks application Makefiles using the standard
Makefile support of RTEMS.

Close #3455.
