Unfortunately due to the complex dependency issues between
Makefile, Makefile.ship and custom/Makefile, parallel GNU make
is NOT recommended. Sorry (tm Canada) :)
Replaced /usr/local with the use of ${PREFIX} in calc Makefiles.
The ${PREFIX} is not the same as ${T}. The ${T} specifies
a top level directory under which calc installs things.
While usally ${T} is empty, it can be specific path
as if calc where "chrooted" during an install.
The ${PREFIX} value, during install, is a path between
the top level ${T} install directory and the object
such as an include file.
Corrected a few more typos in Makefile comments.
Added Makefile.local, a file with a single comment. The main
Makefile includes Makefile.local just before the first all rule.
One may overtide any Makefile setting by modifying Makefile.local.
For example, Makefile.local could force BLD_TYPE:
HAVE_STRING_H:= YES
HAVE_TIMES_H:= YES
SED:= /usr/local/bin/nsed
Added ${LOC_MKF} to specify the make of the file that is
included just before the all file. So one could place
the above override lines into a different file and call
make changing the ${LOC_MKF} value. For example:
make LOC_MKF=Makefile.private clobber all chk
Updated HOWTO.INSTALL to mention Makefile.local.

Added a bunch of information to the near bottom of HOWTO.INSTALL
on calc Makefiles. This information discusses the various
Makefiles found in the calc source.
Added comments in various calc Makefiles about their origin.
In particular, for Makefiles that are constructed such as
Makefile.simple, custom/Makefile and custom/Makefile.simple
there are comments about how they were made.
For all calc Makefiles, including those in sub-directories,
near the top there is now a line of the form:
# SRC: ... some message about the origin ...
Some folks might think: “you still use RCS”?!? And we will say,
hey, at least we switched from SCCS to RCS back in … I think it was
around 1994 ... at least we are keeping up! :-) :-) :-)
Logs say that SCCS version 18 became RCS version 19 on 1994 March 18.
RCS served us well. But now it is time to move on. And so we are
switching to git.
Calc releases produce a lot of file changes. In the 125 releases
of calc since 1996, when I started managing calc releases, there
have been 15473 file mods!
