I'm not aware of any. tcc normally goes directly from C code to
object code without producing an intermediate assembly file.

The resulting .o files should be usable with a linker.

>From a quick glance: the C67 backend looks like it's using a small
assembler internally to make some of the code simpler, but I think
this is just a design choice specific to the C67 backend. When it
needs to emit a machine instruction, it can just pass a string to the
assembly function and have it generate the bit pattern. This probably
also makes it easier to compile inline assembly.
The ARM and i386 backends use a different design, for example see the
store() function in i386-gen.c and notice that it has bit patterns for
several machine instructions hard-coded into it.
