cmd/go: check for another GCC error message
GCC always recognizes the -fsplit-stack option, but then tests whether
it is supported by the selected target. If not, it reports
cc1: error: ‘-fsplit-stack’ is not supported by this compiler configuration
Check for that error message when deciding whether a compiler option works.
