bug#8960: stdbuf on bi-arch systems

[Bruno Haible]

Hi,

The program 'stdbuf' on bi-arch x86 / x86_64 systems cannot work on all kinds
of programs.

I'm using 'stdbuf' from coreutils-8.12 on a glibc x86 / x86_64 system.

The binary built for x86 cannot be called on x86_64 programs:

  $ /arch/x86-linux/gnu/bin/stdbuf -o 0 /bin/pwd
  ERROR: ld.so: object '/arch/x86-linux/gnu/lib/coreutils/libstdbuf.so' from 
LD_PRELOAD cannot be preloaded: ignored.
  /home/bruno

The binary built for x86_64 cannot be called on x86 programs:

  $ /arch/x86_64-linux/gnu/bin/stdbuf -o 0 /arch/x86-linux/gnu/bin/pwd
  ERROR: ld.so: object '/arch/x86_64-linux/gnu/lib64/coreutils/libstdbuf.so' 
from LD_PRELOAD cannot be preloaded: ignored.
  /home/bruno

I would like to have a single binary that works on both x86 and x86_64 programs.

Bruno
