[safestack] Support multilib testing (#98002)
While working on my safestack patches, I noticed that only the default
multilib was tested even though all multilib versions of
`libclang_rt.safestack.a` were built.

This patch fixes this, patterned after the ubsan testing support.

Tested on `amd64-pc-solaris2.11` (`amd64` and `i386`),
`sparcv9-sun-solaris2.11` (`sparcv9` and `sparc`), `x86_64-pc-linux-gnu`
(`x86_64` and `i386`), and `sparc64-unknown-linux-gnu` (`sparcv9` and
`sparc`).
