Suggested by iant@, this change:
- looks for a symbol _rt0_<GOARCH>_<GOOS>_lib,
- if the symbol is present, adds a new entry into the .init_array ELF
section that points to the symbol.
The end-effect is that the symbol _rt0_<GOARCH>_<GOOS>_lib will be
invoked as soon as the (ELF) shared library is loaded, which will in turn
initialize the runtime. (To be implemented.)

So do them all.
Note I had to copy the function into tables_nacl.go. I found that
preferable to creating a new file just to have suitable build
tags. It's likely this function will be mirrored to plan9 and windows
later too, each of the 4 with their own policy of which error values
are common.
The corresponding x/sys CL for this CL is https://golang.org/cl/8190

handoffp by definition runs without a P, so it's not allowed to have
write barriers. It doesn't have any right now, but mark it
nowritebarrier to disallow any creeping in in the future. handoffp in
turns calls startm, newm, and newosproc, all of which are "below Go"
and make sense to run without a P, so disallow write barriers in these
as well.
For most functions, we've done this because they may race with
stoptheworld() and hence must not have write barriers. For these
functions, it's a little different: the world can't stop while we're
in handoffp, so this race isn't present. But we implement this
restriction with a somewhat broader rule that you can't have a write
barrier without a P. We like this rule because it's simple and means
that our write barriers can depend on there being a P, even though
this rule is actually a little broader than necessary. Hence, even
though there's no danger of the race in these functions, we want to
adhere to the broader rule.

This avoids hanging when a Go program uses a FUSE filesystem and the
dup system call has to close a file descriptor. When dup uses
RawSyscall then the goroutine calling dup will occupy a scheduler slot
(a p structure) during the call, and may block waiting for some other
goroutine to respond to the close call on the FUSE filesystem.
Changing to Syscall avoids the problem. This makes Dup a tiny bit
slower but is quite unlikely to make a difference for any real
programs.

Currently, Darwin's siginfo type uses *byte for the si_addr
field. This results in unwanted write barriers in set_sigaddr. It's
also pointless since it never points to anything real and the get/set
methods return/take uintXX and cast it from/to the pointer.
All other arches use a uint type for this field. Change Darwin to
match. This simplifies the get/set methods and eliminates the unwanted
write barriers.

Without some hook like this, it's impossible to get a $ into the generate
command, which is necessary if you're trying to do some shell scripting
or regular expressions.
We could use backslash escaping but that's already tricky enough
because the strings are processed as Go strings. Using $ like this
means we need no more mechanism, just a predefined variable.
We may need to revisit this but I hope we can avoid new quoting rules.
