The --disable-aix64 (--enable-aix64=no) configuration switch claims to remove
ppc64 from the multilib list; however, it doesn't seem to work. On a 32-bit
AIX system, it must be disabled or the build fails when "checking whether the C
compiler works".
The larger --disable-multilib switch works, but is not desirable since it
disables all other libraries including libgcc_s_pthread.
