Go testsuite patch committed: Retain any characters at end of ERROR line

[Ian Lance Taylor via Gcc-patches]

This patch to the Go testsuite driver retains any characters at the
end of an ERROR line in a test.  This is needed for at least one
upcoming test.  Bootstrapped and ran Go testsuite on
x86_64-pc-linux-gnu.  Committed to mainline.
