When I added the "tee" commands to split off command outputs to
a file and the screen, I forgot that the exit status of the make commands
takes the exit status of "tee" which does not ususally have an error and
masks any error in the actual compilation. I added an exit ${PIPESTATUS[0]}
which returns the exit status of the compilation.
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.
This tst was only run if the HOST_CPU of the run matched one
of the pre-existing files. So it was only tested on SL6. Found
that the udunits change never made it to these log files. I
updated the units and introduced only one copy of the files that
all platforms will test against.
Like gcc, swig supports all those -M options. Use them to automatically
manage *_py.cpp dependencies.
Add dependency generation to trickify.mk as well.
Make spends a considerable amount of time checking targets against
built-in implicit rules. Let's turn them off, enjoy some speedup, and
see if anyone was relying on them!

Moving targets to the more correct makefile like defining S_MAIN should
be in make_makefile_src. Moved the makefile_overrides rules read from
directories into their own makefile.
Changed some order only dependencies to actual dependencies. Added a
check in make_makefile_src for new files that should trigger recreating
Makefile_src.
CURDIR is used to produce absolute paths in S_source.d, which allows it
to be included from external makefiles. It is specifically intended to
be included from a Trickified project's user-facing makefile. That is,
the one the user is intended to include in a sim's S_overrides.mk. This
allows the project to automatically build their Trickified object as
part of a simulation build, but only when necessary as specified by the
dependencies.

Trick uses dlsym to dynamically load symbols at run time. At link time,
it cannot be known which symbols will be needed. When presented with a
library, the linker will only link in symbols that are known to be
needed. Therefore, the use of -whole-archive (Linux) or -force_load
(Mac) is necessary when linking a Trickified library into a sim.
We can simplify this by partially linking into an object instead of
creating a library. The linker will link all symbols in an object
regardless of whether or not they are known to be needed.
