Hos can I solve this problem,thanks

I cleared out GOPROXY and it's ok,but run show error....

Error: current platform is not supported
exit status 1

I find the source code.
Supported platforms in the source code has no mips64, mips64le, mips, mipsle
The MIPS instruction set, big- and little-endian, 64- and 32-bit.

If I want to compile the MIPS64,
What should I do?
