9da92cbda9 libgo: Solaris portability fixes.
Only build net/hook_cloexec.go on GNU/Linux and FreeBSD, because those
    are the only systems with accept4.
    
    Add syscall/libcall_bsd.go to define sendfile for *BSD and Solaris.
    
    Revert tcpsockopt_solaris.go back to the earlier version, so that it
    works on Solaris 10.
    
    Always pass the address of a Pid_t value to TIOCGPGRP and TIOCSPGRP.
    
    Include <unistd.h> in runtime/go-varargs.c.

44c925bdb0 libgo: don't provide ustat on arm64 GNU/Linux
This avoids linker warnings when linking against glibc, as apparently
    arm64 GNU/Linux does not support the ustat system call.
    
    Also update to automake 1.11.6, as that is the new GCC standard.

1ca95ba067 syscall: RawSockaddr fix for ppc64, ppc64le
The struct RawSockaddr contains a field Data which
    should be uint8 on ppc64 and ppc64le, but is declared
    as int8 in gccgo.  This change adds a two new files
    which contain the structure declaration for
    RawSockaddr, one with the correct types for for ppc64
    and ppc64le, and the other for non-ppc64 platforms.

f8d9fa9e80 libgo, compiler: Upgrade libgo to Go 1.4, except for runtime.
This upgrades all of libgo other than the runtime package to
the Go 1.4 release.  In Go 1.4 much of the runtime was
rewritten into Go.  Merging that code will take more time and
will not change the API, so I'm putting it off for now.

There are a few runtime changes anyhow, to accomodate other
packages that rely on minor modifications to the runtime
support.

The compiler changes slightly to add a one-bit flag to each
type descriptor kind that is stored directly in an interface,
which for gccgo is currently only pointer types.  Another
one-bit flag (gcprog) is reserved because it is used by the gc
compiler, but gccgo does not currently use it.

There is another error check in the compiler since I ran
across it during testing.

	* Makefile.am (go_cmd_go_files): Sort entries.  Add generate.go.
	* Makefile.in: Rebuild.

85c2f96c1c syscall: fix creds_test to reliably close os.File
Uncovered by Uros Bizjak.

Before this patch the test would close the file descriptor but
not the os.File.  When the os.File was GC'ed, the finalizer
would close the file descriptor again.  That would cause
problems if the same file descriptor were returned by a later
call to open in another test.
