Top-level patch committed: Add check-gotools to check-go

[Ian Lance Taylor]

I've committed this patch to the top level Makefile.def so that `make
check-go` will run `make check-gotools`.  Bootstrapped and ran Go
testsuite on x86_64-pc-linux-gnu.  Committed to mainline.

This patch may cause new test failures on other systems.  Please let
me know about them.  I don't anticipate anything in particular, but,
who knows.
