    • libgo: use Solaris sendfile lib, fix Solaris _in6_addr_t fields · 88cf4de8 
          
    Before Solaris 12 the sendfile function is found in -lsendfile, so look
    for it there.
    
    Solaris 12 adds some more types that use _in6_addr_t, that need to be
    edited in mksysinfo.

    • re PR go/68255 (cgo-generated constructor not being called) · ea5c2003 
      	PR go/68255
    cmd/go: always use --whole-archive for gccgo packages
    
    This is a backport of https://golang.org/cl/16775.
    
    This is, in effect, what the gc toolchain does.  It fixes cases where Go
    code refers to a C global variable; without this, if the global variable
    was the only thing visible in the C code, the generated cgo file might
    not get pulled in from the archive, leaving the Go variable
    uninitialized.
    
    This was reported against gccgo as https://gcc.gnu.org/PR68255 .
