This is not how automake documents these variables. The doc (node
"Libtool Flags") says that I can augment only two variables:
  - libgnu_la_LIBADD, reserved for .lo or .la files, not -L, -l, -rpath options,
  - libgnu_la_LDFLAGS.

So, for libraries, there is no *_LDADD variable.

And for executables, an *_LDADD variable exists, but the automake doc says
the opposite of what you say:

   `PROG_LDADD' is inappropriate for passing program-specific linker
   flags (except for `-l', `-L', `-dlopen' and `-dlpreopen').  So, use the
   `PROG_LDFLAGS' variable for this purpose.
