On MacOS, brew installs /usr/local/bin/python but the Python prefix is not /usr/local/bin
Use the python command sys.exec to get the correct directory, instead of the ad hoc self.prefix
previously used

This was a bear to debug; been driving me nuts since I started using spack.
Since spack passes PYTHONHOME down to package builds in the environment
it was passing PYTHONHOME of /usr/local/bin to the PETSc build that uses Python so
the PETSc Python ./configure errored immediately with

ImportError: No module named site

since python could find no python modules. Todd Gamblin pointed out that my first try to fix
this was wrong since it assumed the spack python was the same python used to run spack. Elizabeth Fischer
suggested how to get it to work also with python3

Add a package for ant, a java build tool.

Add a package that installed the pre-built maven distribution.

I've given up, for now, on building maven from source.  That processed
stumbled on two points before I gave up:

1. It downloaded several hundred .{pop,jar} files and I despaired of
   figuring out some way of mirroring and checksumming them; and

2. It exploded complaining about too many unacceptable license files,
   which seems odd in its own source tree.

Perhaps someone with more Java fu that I admit to can figure it out.
In the meantime, this is useful.

* libsodium: add latest versions, fix old versions

older versions of libsodium were added to an "old" subdirectory

prerequiste for the latest develop version of flux

Pkg-config depends on glib which depends on pkg-config. As a result,
pkg-config used to build glib internally. However, this fails on Mac.
Building pkg-config with an internal glib is now a variant, turned on
by default, and required to build glib.

* Add patch allowing GCC 6 to compile GCC 5

* Expand patch version range
