Хорошего описания я не нашёл, к сожалению ;(

вот всё что есть на сайте:

  4.1. Biarch Systems


The directories like /usr/lib64 and /usr/X11R6/lib64 are used next to 
the usual /usr/lib and /usr/X11R6/lib directories on biarch systems. 
This is because two variants of the same libraries must coexist on such 
systems to allow running both 32-bit and 64-bit applications in 
parallel. The 64-bit libraries are installed in lib64 directories and 
32-bit libraries in the lib directories. The macros 
[[SUSE_Package_Conventions/RPM_Macros#spc_rm_lib %_lib] and 
[spc_rpm_macros.html#spc_rm_libdir %_libdir] do this.

Special packages are created for the biarch systems that include only 
the 32-bit libraries. Any other files are not needed because these 
libraries can use architecture independent files from the 64-bit 
packages. They are even able to execute 64-bit helper binaries. 
Therefore, these are shared as well and are installed into lib on all 
architectures instead (and not %_lib). See the part about --libexecdir 
in the following section.

Видимо всё остальное надо смотреть в пакетах:

В частности там лежит пачка пакетов содержащих в имени 32bit.
