I think you missunderstand my post. The directory for 32/64bit libaries
shouldbe prefix/lib and prefix/lib64 respectively.
But current ofed1.2 I saw only prefix/lib64 directory, ie 64bit libs only.

We have customers that still use 32-bit userspace applications.
It would be beneficial for them if they can obtain 32bit libs and execs from
ofed1.2 in order to run their applications without recompiling them, because
for some 32-bit applications recompiling is not an option.
