Clean up warnings that show up on newer compilers. Many of these warnings
are related to obsolete c library features or language features. This does
not clear up warnings in code generated by bison or flex.
With a pattern rule, the recipe will only be executed once, even when
the rule has multiple targets. Using this to handle the output from
bison is included as an example in the GNU make manual.
This fixes the makefiles so that bison-generated header files will be
regenerated if they are deleted.
The current bison (3.7) generates a *.cc file that includes the header
it generated. For parse.cc this would be parse.hh. Right now, we rename
this header to have a common name used in other files, but this results
in a compile error for the parse.cc file:
parse.cc:462:10: fatal error: parse.hh: No such file or directory
462 | #include "parse.hh"
| ^~~~~~~~~~
Fix this by telling bison to output the header file to the correct
filename in the first place so that we don't have to rename it.
(using the --defines instead of -d option).
This looks like a bison specific option not available in Posix yacc;
but looks like we're requiring bison anyway.

In PR #300, @xdch47 pointed out a stable way to fix parallel
installation problems.
This fix applied the method, thanks!

bison 3.4.2 complains when encountering '%pure-parser':
"warning: deprecated directive, use ‘%define api.pure’"
A quick google suggests this option has been around since at least
2012, maybe longer, so probably safe to replace.

bison 3.4.1 writes the header file before the c++ file. Our makefile
rules make the header files depend on the c++ files, so we need to
fix the timestamps accordingly.
Arrays type match if they have a common parent, instead of the
element type. Now (un)signed & std_logic_vector types do not match,
as it should be in VHDL.
