feat(build): Enable --with[out]-EXECUTABLE=PATH configure flags for tooling dependencies

Swaping out custom m4 work with an existing autoconf-archive macro nets
us another way to enable or disable specific tools, but more importantly
both the new and existing ways are become properly documented in the
output of `./configure --help`. This shouldn't change the current way
`./configure EXECUTABLE=PATH` can be used to configure tools, just adds
another route to get there using `--with[out]-EXECUTABLE=PATH.
