[meta-ti] Backport request for thud

[Paul Barker]

I'm currently seeing build failures on the thud branch with meta-ti under Centos 7 and Centos 8. As /lib and /lib64 are links to /usr/lib and /usr/lib64 respectively, the logic in ti-unpack.inc is looking for the 32-bit C library under /lib32 which doesn't exist.

Could you backport 6f80b1e5595a13eec465581cfb352efcb0286bc8 from master to thud to fix this?

Thanks,
