dev-lang/tcc-0.9.23-r1 fails to compile complaining of an unsupported CPU when attempting to build using 32bit x86 gcc installed via crossdev on an AMD64 system. TCC builds normally on this CPU when running a full 32bit system. So it stands to reason that it should build using a 32bit compiler for cross-development.
