Thanks for the hint.
I pushed a fix for this.

It's testing that ".byte expression" and similar directives are
handled for expressions that are constants, but gas does not know the
fact that they are constant at the time the directive is assembled.
So target code emits a fixup but by the time md_apply_fix is reached,
gas should have resolved the expression down to a constant and
fx_addsy and fx_subsy are both NULL. md_apply_fix should set fx_done
and write out the value.
In the s12z case it looks like you're missing support for .dc.w/.short
since md_apply_fix doesn't handle BFD_RELOC_16. Note that your target
doesn't need to support 16-bit relocs in object files (just like it
currently does not support 8-bit relocs but does handle BFD_RELOC_8
fixups in md_apply_fix).
