Building emacs on darwin throws an error when trying to build an Emacs
app in the nextstep/Emacs.app path of the build tree. For now, disable
building this app.

It's possible to enable building the app also; Homebrew offers options
to this effect, and also adds Mac-specific options for starting the
emacs daemon. However, for the sake of simplicity and getting a
workable up-to-date emacs installation on my machine as quickly as
possible, this commit focuses on a minimal viable modification.

Spack needs to pass information about where the linker
can find `libintl`.  We're currently using `LDFLAGS` to do so.
The `LDFLAGS` info is pasted into the command line upstream
of the a file (`libgit.a`) that includes unresolved symbols that
need that library.  This fails on Ubuntu, although it seems to
work on CentOS (see #6841).

This change allows git to build on a Ubuntu 16.04.3 droplet.

TODO: test on other platforms...

* Add a bit of useful commentary

* perl-xml-simple: Create new package

Remove unnecessary double brackets in ADIOS2 and gearshifft packages.

* Upgrade recipe for parmetis to be a CMakePackage

+ Eliminate `install` method (use the one from CMakePackage).
+ Move configure options to new method `cmake_args`
+ Move special install instructions for DarwinOS to a `run_after` method.

* Fix run_after section; Remove variant +debug.

Control the find_package of the PNG variant explicitly.
This avoids picking up an "external" PNGwriter install in
case `~png` is picked by changing the default "AUTO" search
to explicit "ON" (required) of "OFF" (ignore if exists).
