Before Solaris 12 the sendfile function is found in -lsendfile, so look

Solaris 12 adds some more types that use _in6_addr_t, that need to be
edited in mksysinfo.

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 .

> This is causing a bootstrap comparison failure in gcc/go/gogo.o.
I've had a look at this and the trigger is the
aarch64_use_constant_blocks_p change which appears to be causing a
bootstrap comparison failure because of differences to offsets when
built with debug and without debug. I don't think the problem is
specifically in the backend but this needs some careful
investigation. For now, in the interest of go bootstraps continuing on
trunk - I'm proposing a patch that partially rolls back the change in
aarch64_use_constant_blocks_p and am still looking into the issue but
it will take me some more time to get to the bottom of the issue.
Bootstrapped on aarch64-none-linux-gnu including (c,c++ and go) -
testing finished ok.
