ld.so for multiarch and multilib installed at same time

On amd64 system:

 libc6-i386  make /lib/ld-linux.so.2  link to /lib32/ld-linux.so.2 and link to
       /lib32/ld-2.18.so

libc6:i386 make /lib/ld-linux.so.2 link to /lib/i386-linux-gnu/ld-2.18.so

when these 2 packages installed at the same time
     /lib/ld-linux.so.2 is linked to /lib/i386-linux-gnu/ld-2.18.so

And dpkg is happy about that this happens.


On mips64el system:

libc6-mips32 make /lib/ld.so.1 link to /lib/ld-2.18.so
         (yes, quite strange, mips system asks for use /lib as o32
multilib path)

libc6:mipsel make /lib/ld.so.1 link to /lib/mipsel-linux-gnu/ld-2.18.so

When try to install these 2 packages both, dpkg will be unhappy:

dpkg: error processing archive libc6_2.18-4_mipsel.deb (--install):
 trying to overwrite '/lib/ld.so.1', which is also in package
libc6-mips32 2.18-4
Errors were encountered while processing:


I also tried to repack libc6:mipsel to link /lib/ld.so.1 to
/lib/mipsel-linux-gnu/ld.so.1
instead of ld-2.18.so directly.
It aslo has the same problem.


Is it a problem of dpkg or eglibc?
