m4 exited immediately (causing the nettle build to fail).

Tracked down a fix via the Homebrew recipe. I'll send a note to the
`bug-m4@gnu.org` list to ensure that upstream knows about it.
* Fix gcc@5.5.0 on OS X 10.13.5
gcc@5.5.0 failed to build on my OS X 10.13.5 box.
I found/modified a patch in the MacPorts world that traced back to
Homebrewy, https://trac.macports.org/ticket/56502#no1
The issue has also been reported to gcc,
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83531
I eventually discovered a nearly identical version of the patch at
Homebrew.
https://github.com/Homebrew/formula-patches/blob/master/gcc%405/10.13_headers.patch
gcc builds with this and I can compile many things, but e.g. curl and
cmake both fail. As @davydden and others observed in #1847, it seems
to be an apple thing.
* Fix mistaken change to patch when clause (added :)
I mistakenly deleted a colon from the
'darwin/gcc-7.1.0-headerpad.patch'.

* Added minuit package
* Removed default method and template
* Different URLs for old versions
* Patches for versions down to 1.5.0
* Reverted ROOT package changes
* Removed print statement
* Added checksums for older versions
* Consistent version names
- pytest was not reporing the correct version from pytest.__version__.
It reported 'unknown'
- this fixes issues on some systems where system-installed pytest plugins
would try to use the version and convert it to an int
* SAMRAI: remove dependency on boost for samrai 3.12.0 or later versions, but keep the older versions ccontinuing working with boost 1.64.0 or earlier. Also, the older versions cannot compile with boost 1.65.0 or above. (#8491)
* SAMRAI: fix typos of comments and remove obsolete code.
* Updating Nalu now that it can build with shared libraries and adding the new Nalu-Wind wind energy focused application.
* Explicitly turn off TPLs for Nalu when not enabled.
* Adding patch for OpenCV to fix a conflict between an OpenCV and a CUDA header file
* Added patch command to package.py file for OpenCV SPACK package.
* Adding version range for patch.
* shortening comment lines, since testsuite failed
* Add changes to the Krell packages with version updates and ranges for the latest release.
* Add reviewer requested changes. Remove preferred clauses and update the qt version for the cbtf-argonavis-gui@develop
* Trigger integration/test restart
* Add patching for xlf when %clang. Changes are effective only when Fortran compiler is 'XL'.
* Use the right version for trilinos when patching for seacas.
