So you want ev56 scheduling with pca56 instruction support to get this to assemble? IIRC, the scheduling code between the two processors doesn't differ...only it's instruction support. '-mcpu=pca56 -mno-bwx' may allow it to compile and assemble while disabling generation of code to use the BWX instruction sets (which aren't present on ev56, but are on pca56).
Minor correction: ev56 does have the BWX extension, that's what makes it different from ev5 (besides a structure shrink, IIRC). So the table of instruction set extensions inside the 21164 family should read:
BWX MVI ev5 - - ev56 X - pca56 X X
