I've applied the patch, so it should now be available in the main repo :)

I was able to build go@1.16 as-is and with the conditional switched, so
it used gccgo to bootstrap go@1.16. Additionally on my x86_64 machine
using emulation I was able to build go@1.16 for powerpc64le. On the
powerpc64le box I have access to I was able to build gccgo and I'm still
building out to go@1.16.

My only concern about the patches is that I've been burned before about
pushing updates to go packages, where some seem to have insufficient
testing and then they'll build and fail. So in the meantime I've pushed
the go@1.16 patch.
