Fixes [YOCTO #16058]

Enable dynamic linking with LLVM (link-shared) for all rust variants
(native, nativesdk and target) via a PACKAGECONFIG option, enabled
by default. This prevents segmentation faults when reusing sstate
artifacts built with different host toolchains.

Update multilib library symlinking to include shared libraries and
adjust the rust selftest to install llvm so the dynamically linked
compiler can run correctly.

Sunil,

Please simplify the reproduction and report this upstream to GCC folks.

reply with the bug if any.

The goal is that eventually, 5+ years, we could revert this change
if this is really an upstream bug.
