Made a couple of changes in ICG source code to handle clang API differences. Encapsulated
differences in ifdefs. Added libclangSupport to ICG link line.
* major refactor of test_linux workflow
* oracle linux, almalinux, and debian 11 added to workflow
* #1243 ac_path_progs does not cache negative result like ac_path_prog. Strange. Fix bad python and python-config behavior
* add or statement in case behavior changes across autoconf versions
* all OSs now test both python 2 and python 3
* #1232 add lib paths to LDFLAGS in configure script #1236 ignore configure on github by adding linguist commands to .gitattributes

To support Ubuntu 20.04 we must support new versions of python and gtest. Python has changed the way it provided libraries using python-config, so adjustments had to be made. I've completely ditched the built in autoconf function for finding python, because it adds a bunch of extra flags we don't need for Trick.
Now when we look for python with configure, it will search for python in this order:
python${PYTHON_VERSION}
python
python3
For python-config, it will search in this order:
python<major_version.minor_version>-config
python<major_version>-config
python${PYTHON_VERSION}-config
python-config
python3-config
Instead of python-config --ldflags, we are using python-config --libs
This only gets the flags we need.
For python >= 3.8 we use
python-config --libs --embed
this way it will add -lpython to the flags
If we can't find python in the configure script then search for
python3. If python3 is found use python3-config to get the
include directories and libraries. Call python scripts using the
PYTHON environment variable.
Added a new configure arugument "--enable-32bit". If enabled,
TRICK_FORCE_32BIT is automatically set for building Trick and for
all sims built. Changed the ARCH and added -m32 in the configure
script if 32bit is enabled. This changes the configure script to
test for 32bit libraries.
Found if --without-x was specified, that automatically caused an
error condition in the configure script. Fixed that and only
tested for X windows headers and libs if X is included. Excluded
a couple of directories from compiling if X is not included.
Didn't seem to be a problem with java.
If we are on a Mac, use xcrun to find the standard include directories.
Some of the makefiles in data_products look for libxml2 which requires
them to get the same change as the configure script.
When compiling Trick with the --with-tpro option for use of a real-time clock, the TPROCTE_HOME variable was being assigned the contents of the withval variable instead of being assigned to the TPRO_HOME variable. The TPROCTE_HOME variable was never used and the TPRO_HOME variable will always be an empty string. Thus, the configuration file will always check for only /h/tpro.h instead of <user-provided-path-to-tpro>/h/tpro.h
Other things I tried:
1. Pass the full path of the library directly to the linker.
Doesn't work for 32-bit builds because ICG needs the 64-bit version.
2. Use -static to have the linker statically link in the library.
Doesn't work because there is no 64-bit static library on default
installs.
Fixes#525
Added echos to all compile commands to append to MAKE_out. tee'd
the output of the compile command so that it will go to both the MAKE_out
file and the screen.
