on i386 libc.so.6 not found and usable

[Christoph]

The following bug happens within i386 architecture-structures. I have tested it with Ubuntu 14.04 (tahr) and 14.10 (unicorn).

strace tlsdate -V
...
open("/usr/lib/libc.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat64("/usr/lib", {st_mode=S_IFDIR|0755, st_size=20480, ...}) = 0
writev(2, [{"tlsdate", 7}, {": ", 2}, {"error while loading shared libra"..., 36}, {": ", 2}, {"libc.so.6", 9}, {": ", 2}, {"cannot open shared object file", 30}, {": ", 2}, {"No such file or directory", 25}, {"\n", 1}], 10tlsdate: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
) = 116
exit_group(127) = ?
+++ exited with 127 +++

----

If I symlink the libc.so.6 to search path, I get a "permission denied" error.
ln -s /lib/i386-linux-gnu/libc-2.19.so /usr/lib/libc.so.6

strace tlsdate -V
...
open("/usr/lib/libc.so.6", O_RDONLY|O_CLOEXEC) = -1 EACCES (Permission denied)
stat64("/usr/lib", {st_mode=S_IFDIR|0755, st_size=20480, ...}) = 0
writev(2, [{"tlsdate", 7}, {": ", 2}, {"error while loading shared libra"..., 36}, {": ", 2}, {"libc.so.6", 9}, {": ", 2}, {"cannot open shared object file", 30}, {": ", 2}, {"Permission denied", 17}, {"\n", 1}], 10tlsdate: error while loading shared libraries: libc.so.6: cannot open shared object file: Permission denied
) = 108
exit_group(127) = ?
