[6.32/master] Fail to materialise simbols from `libMatrix`

Description

Any code run through TInterpreter::Declare that needs symbols from libMatrix ends up in

cling JIT session error: Failed to materialize symbols: { (main, { _ZN8TVectorTIfE8StreamerER7TBuffer, _ZN8TVectorTIfE8Delete_mEiRPf, _ZN8TVectorTIfE4DrawEPKc, _ZNK8TVectorTIfE5PrintEPKc, _ZN8TVectorTIfE5ClassEv }) }

See the simple reproducer below. Here is what I get with two different ROOT versions on lxplus:
