	other/PR56780
	* 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.
