dev-lang/go: 1.12.1 bump and cross compile fix
dev-lang/go, before this commit, failed to build in an environment generated by sys-devel/crossdev for two reasons: 1. The bootstrap download package matched the target rather than host arch. We can't determine the host arch based on use flags, so we need to download all bootstrap packages. 2. The GOROOT_BOOTSTRAP environment variable matched the host rather than target arch. To fix this, we need to pass CBUILD to the calls to go_os and go_arch. This fixes both issues for a successful cross-compile. Closes: https://bugs.gentoo.org/671394 Package-Manager: Portage-2.3.62, Repoman-2.3.12 Signed-off-by: William Hubbs <williamh@gentoo.org>
