	cannot be linked dynamically.

	tests-static.

	* libc.map: Add __nss_passwd_lookup, __nss_group_lookup, __nss_next.

	* misc/error.c: Pretty print.

	* Makerules (libc_nonshared-name): Remove variable.
	(installed-libcs): Use libc-name instead.
	($(inst_libdir)/libc.so): Likewise.  Remove explicit reference to

	libc.a.  Remove explicit reference to dynamic linker.
