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}} \
