I built a separate package for 32-bit RHEL 5.11 (again, using a local installation path).  After installation, I observed that the -hash option of the openssl command (and hence the c_rehash utility) computed incorrect subject hashes for the issuer certificates in the cache.  Identical certificates from the 64-bit installation were installed but the hash values were different.  Tracing the operation of the s_client module with strace indicated that the hash values computed internally matched the hash values produced on the 64-bit system.  I replicated the symbolic links for the issuer certificates from the 64-bit system to the 32-bit system and the certificates presented by the remote server for my application were verified.

FWIW: I've downloaded and built openssl-1.0.1s on my EL 5.11 box in both 
32bit and 64bit mode (I needed to hack ./Configure for that, BTW).  The 
resulting
  openssl x509 -hash
command prints out the exact same hash for both the 32bit and 64bit 
versions.
