	* libiberty/configure.ac: Move test for --enable-install-libiberty
	outside of the 'with_target_subdir' test so that it actually gets
	run.  Add output messages to show the test result.
	* libiberty/configure: Regenerate.
	* libiberty/Makefile.in (install_to_libdir): Place the
	installation of the libiberty library in the same guard as that
	used for the headers to prevent it being installed unless
	requested via --enable-install-libiberty.
