libgo runtime needs an update.
gccgo build scripts need to support loongarch64.

Do I have to use gccgo? Since the version of go in gcc is relatively low, this
transplant requires some work. We have discussed with our colleagues who are
working on the Go compiler that if it is not necessary to use gccgo, we will
not do the transplant.

Thanks!

GCC will eventually bump the Go version but it requires some non-trivial work:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108682#c6.  So I'd like to defer
the transplant after Ian completes all these.

FWIW one nice aspect of gccgo is we don't need a pre-installed Go binary to
build it.

Do you know when the version of gccgo will be upgraded?

No but anyway we should be struggling to make it match the latest Google Go
compiler.  If we cannot keep up one day I guess gccgo will be simply removed.

Ok, I see. Thanks!

Yes. In Freedesktop SDK project[1], we need gccgo to bootstrap gc go.
