That's why my private patch for mips64-linux has:
%{mips1:-D_MIPS_ISA=_MIPS_ISA_MIPS1} \
%{mips2:-D_MIPS_ISA=_MIPS_ISA_MIPS2} \
%{mips32:-D_MIPS_ISA=_MIPS_ISA_MIPS32} \
%{mips3:-D_MIPS_ISA=_MIPS_ISA_MIPS3} \
%{mips4:-D_MIPS_ISA=_MIPS_ISA_MIPS4} \
%{mips5:-D_MIPS_ISA=_MIPS_ISA_MIPS5} \
%{mips64:-D_MIPS_ISA=_MIPS_ISA_MIPS64} \
%{!mips*: \
%{mabi=32|mabi=o32|!mabi*:-D_MIPS_ISA=_MIPS_ISA_MIPS1} \
%{mabi=n32|mabi=64|mabi=n64:-D_MIPS_ISA=_MIPS_ISA_MIPS3}} \
