+	* device_table.c (update_for_binary_section): Abort if we find an
+	.interp section, which indicates the need for shared libraries to
+	be loaded.
+
 	* emul_unix.c (do_unix_{time,gettimeofday,getrusage}): Add support
 	for time, gettimeofday, and getrusage system calls.
 	({solaris,linux}_descriptors): Add new system calls.
