    When I updated to Go 1.8, the initsig function moved from
    signal1_unix.go to signal_unix.go, and lost a gccgo-specific change in
    the move.  Add it back.
    
    This would have been caught by the misc/cgo/testcarchive tests in the
    gc repository, but we don't run those in the gccgo repository.  We
    should fix that, somehow.

    I typoed the argument passed to getcontext in getTraceback, and the
    error was hidden by ucontext_arg.  This would have been caught by some
    of the runtime package tests, but we don't run most of them because
    they rely on `go build`, and the go tool is not available while
    running the libgo testsuite.  We should fix the libgo testsuite,
    somehow, so that they run.
