Howdy! Nowadays, most of us have multiprocessor desktops, but so far as
I can tell, when compiling elisp to .elc (or .eln) during make of Emacs,
the build only takes advantage of one processor. Is there a magic option
to configure that I missed that will use all my processors to compile
elisp during the build?

You mean, "make -jN" where N is the number of execution units?

Precisely, but that seems to work for building Emacs's .c files but not
for compiling the elisp files. I may have screwed something up in my
build; if it is expected to work, that would be useful information
because then I could try to debug what has gone wrong.

-jN works on Elisp files too.
Please note that some .el files take a while to build and they are a
dependency for a posterior build product, so it is possible that at some
time only one .el file is being compiled. Also, there are other products
that take a long time to build, so you could get the impression that the
build is working single-threaded.
But, for the most part, the build of the Elisp files is highly
parallized.

No, it should compile the *.el files in parallel as well. It works
here as expected, I use it all the time.
