strace of  'nm ./latent_entropy.o'

Description of problem:
I have llvm-libs.i686 and llvm-libs.x86_84 installed. On some binaries, nm and ar will throw an error message:

% file latent_entropy_plugin.o
latent_entropy_plugin.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), with debug_info, not stripped
% nm latent_entropy_plugin.o | grep bfd
nm: Failed to load plugin '/usr/bin/../bin/../lib/bfd-plugins/LLVMgold.so', reason: /usr/bin/../bin/../lib/bfd-plugins/LLVMgold.so: wrong ELF class: ELFCLASS32

The weird thing is that strace shows it looks in lib64 and finds the correct .so, and then turns around and searches for it *again* in the wrong lib.
From the strace:
