Go testsuite patch committed: Recognize errorcheckdir -n

[Ian Lance Taylor]

This patch to go-test.exp recognizes errorcheckdir -n, as used by the
updated bug345 test.  The -n option is meaningful for the gc compiler,
but irrelevant for gccgo.  Bootstrapped and ran Go testsuite on
x86_64-pc-linux-gnu.  Committed to mainline.

* go.test/go-test.exp (go-gc-tests): Recognize errorcheckdir -n,
for bug345.go.
