I've committed a patch to update libgo to the 1.11 release.  As usual
for these updates, the patch is too large to attach to this e-mail
message.  I've attached some of the more relevant directories.  This
update required some minor patches to the gotools directory and the Go
testsuite, also included here.  Bootstrapped and ran Go testsuite on
x86_64-pc-linux-gnu.  Committed to mainline.
