Hmmn,

I've done this, and GNU ELPA has already built version 1.0.1 of the
package as intended.

But how do I install it from Emacs 26.1, iow, how do I upgrade it?

1. This doesn't work:

   emacs -Q
   (package-initialize)
   (package-refresh-contents)
   (package-install 'flymake)

Presumably because in Emacs 26.1 flymake is already a "built-in" package
(though at version 0.3)

2. If I do it interactively from the package menu, it works.  Go
into the menu with M-x list-package, mark flymake 1.0.1 with 'i', then
type x.

3. This does work but seems pretty brittle

(package-initialize)
(package-refresh-contents)
(package-install #s(package-desc flymake
                (1 0 1)
                "A universal on-the-fly syntax checker"
                ((emacs
                  (26 1)))
                single "gnu" nil
                ((:url . "http://elpa.gnu.org/packages/flymake.html")
                 (:keywords "c" "languages" "tools"))
                nil))

The reason I want to do this programatically is so I can test eglot, a
package that depends on flymake, from a "make check" target in a
Makefile.
