One answer would be to use an implicit DLA for N64, and LA otherwise.
I was thinking more about explicitly written LA vs. DLA.

All this demonstrates once again that the whole built-in macro stuff
in the MIPS assembler was a design blunder from day one.  Sigh.

Fortunately, GCC no longer uses any of this...
