Configure zlib with --enable-host-shared for shared bfd

When bfd is configured as a shared library, we need to configure zlib
with --enable-host-shared since zlib is used by bfd.

	PR ld/18355
	* Makefile.def: Add extra_configure_flags to host zlib.
	* configure.ac (extra_host_zlib_configure_flags): New.  Set
	to --enable-host-shared When bfd is to be built as shared
	library.  AC_SUBST.
	* Makefile.in: Regenerated.
	* configure: Likewise.
