coreutils: Remove 8.19 reference
coreutils: Guard against compiler not supporting __builtin_stpncpy_chk

From https://lists.macosforge.org/pipermail/macports-dev/2011-July/015263.html:

5) Building with a compiler that doesn't support newer __builtins

If your port uses MacPorts compilers rather than the default compiler,
you may run into trouble with string functions.  You'll see errors at
link time about undefined __builtin_* functions.  If this happens, you
may want to compile with -D_FORTIFY_SOURCE=0 to tell the headers to
use unfortified versions which do not use compiler builtins.
coreutils,gettext: don't change hash except for darwin

Also some style cleanup.
Note that defining an empty-string variable *does* change the hash.
I would like to change this behaviour one day
(clean up attrs when compiling the derivation).
darwin: update coreutils and other fixes (close #939)
Darwin support for Go 1.1 (close #952)
fail2ban: fix build on darwin (close #933)
emacs24: fix build on darwin (clos #932)
djvulibre: fix build on darwin (close #931)
deluge: fix build on darwin (close #930)
emacs24: fix license typo, change indentation

Note that the double-quote "indented strings" strip indentation,
so this ugly style was pointless.
enscript: fix build on darwin (close #933, really this time)
ImageMagick: update 6.7.5-3 -> 6.8.6-9 (close #960)
gamin: don't change hashes on non-darwin

Sorry, I didn't realize this is "fam" which is used in glib.
libffi: disable tests on FreeBSD as well

There are strange build failures of expect. Ikwildrpepper says the bash
eats all CPU, but the build is stuck.
libreoffice: don't build all languages until we use multiple-outputs to minimize disk usage
libreoffice: fix build
haskellPackages.snapletAcidState: New Expression (close #966)
haskellPackages.amqp: New expression.
Close #965.
tinc: Update to 1.0.22
close #957
libffi on FreeBSD: remove unsupported "-r" option to ln

Done without changing hashes on other platforms.
Sometimes I forget that GNU's not UNIX.
