Description: Add CPU arch conditions to test 05_32_bits
 This should solve FTBFS on riscv64 as well as other platforms that
 does not support -m32 or -m64 options.
 .
 Tested on Debian riscv64 on QEMU and worked fine.
 .
 I have also submitted a [PR](https://github.com/haampie/libtree/pull/82)
 to upstream, but they haven't merged it yet.
 .
 I've only included part of platforms here, including x86_64 and
 i386, since I don't know the exact output of uname -m on those
 platforms. Feel free to append more platforms to the list.
