Update go to 1.1.2.

go1.1.2 (released 2013/08/13) includes fixes to the gc compiler and cgo,
and the bufio, runtime, syscall, and time packages. See the change
history for details. If you use package syscall's Getrlimit and
Setrlimit functions under Linux on the ARM or 386 architectures, please
note change 55ac276af5a7 that fixes issue 5949.

This is a leaf package, so it should be ok during the freeze.
