In some assembly files there are some instructions that only valid for 64BIT, but those files can be compiled for 32BIT and cause build errors. So, replace those instructions with macros: li.d --> LONG_LI (li.w or li.d), addi.d --> PTR_ADDI (addi.w or addi.d). BTW, Re-tab the indention in the assembly files for alignment.
