+Using DESTDIR or INSTALL_ROOT is enabled, with INSTALL_ROOT being the default
+value for DESTDIR, and the rest of the make file using only DESTDIR.
+It works as follows:
+ $ make install DESTDIR=/path/to/image
+overrides the in-makefile set DESTDIR, while both
+ $ INSTALL_ROOT=/path/to/image make install
+ $ make install INSTALL_ROOT=/path/to/image
+use DESTDIR=$(INSTALL_ROOT), even if DESTDIR eventually is defined in the
+environment, because variable-setting priority is
+1) commandline
+2) in-makefile
+3) environment

+Note: This only applies to the Expat library itself, building UTF-16 versions
+of xmlwf and the tests is currently not supported.
