Go 1.20 requires a minimum version of go 1.17.13 to bootstrap.
https://go.dev/doc/go1.20#bootstrap
As Go 1.4 was the previous version that could be compiled with C, there is now
no way to bootstrap go with a C compiler, unless we use a two-stage bootstrap:
- build host-go-bootstrap-1.4-20170531
- build host-go-bootstrap-1.19.10 with host-go-bootstrap-1.4-20170531
- build host-go-1.20 with host-go-bootstrap-1.19.9
This is implemented in this commit first, before upgrading host-go to 1.20.
Note: the .patch files from package/go version 1.19.x are not necessary for
package/go-bootstrap-stage2 and have not been included there.
