    go: fixes for cross-canadian builds
    
    * Add patch for go's make script to allow for
      build system != host system
    
    * Add dependencies on the appropriate crosssdk recipes,
      and use the crosssdk C compiler and linker
    
    * Remove bashism in the wrapper script
    
    * Restrict installation to only the tool binaries
      to address some packaging errors

+Subject: [PATCH 8/8] make.bash: add GOHOSTxx indirection for cross-canadian
+ builds
+
+Add environment variables for specifying the host OS/arch
+that we are building the compiler for, so it can differ from
+the build host OS/arch.
