The 64-bit ones? No, Debian wanted to allow 32-bit *-linux-gnu targets
that provice all three ABIs, while still defaulting to o32. The associated
GCC configure option is --enable-targets=all. (Confusingly different from
the binutils meaning, but there you go. That choice of name wasn't a MIPS

Indeed. And MIPS GCC requires 64-bit HWIs regardless of whether you're
compiling for a 32-bit or 64-bit target.
