fix issue that
| Error: Transaction test error:

Pass ${libdir} to configure option --libexecdir of libunwind that it installs
    plugin libraries to /usr/lib{,64} rather than /usr/libexec/

This does not look like a correct fix. Helper executables should not
go to libdir, they should indeed remain in libexecdir.

When multilib issues happen, there's an unfortunate tendency to not
look into what the differences actually are, and where they originate.
Please do so first, and then we'll work towards a fix.

Yes, you are right. Files under /usr/libexec of libunwind are all helper tools. They should
remain in /usr/libexec.

Then how about fix it with MULTILIB_SCRIPTS, I have send a V2 patch. Please review again.
