There is mips64 support (evbmips). The kernel is 64 bit but the
userland is still 32 bits. Last I checked dynamically linked 64 bit
binaries were crashing due to dynamic linked missing relocation types/bugs.
You can build mips64 either big or little endian and we do complete
builds every day (here):

Is there a 64 bit emulation for mips? qemu...
I am willing to help, but I am as always stressed for time. You can
also cross build everything which helps tremendously.
