I think I see what's going on: in gnat.log, I find

If running the gnat.dg testsuite, lib/gcc-dg.exp is now calling
check_linker_plugin_available early, which ultimately calls
${tool}_target_compile. For all languages but Ada,
${tool}_target_compile can compile .c files just fine, but
gnat_target_compile (which uses gnatmake) cannot, so it falls back to
directly calling gcc_target_compile in that case. gcc_target_compile
relies on GCC_UNDER_TEST being set, which in this case hasn't yet
happened, thus the error.
My solution (a hack, actually) is to move the initialization of
GCC_UNDER_TEST in gcc-dg.exp before the calls to
check_linker_plugin_available. x86_64-unknown-linux-gnu testing in
progress, will commit once that's finished.
Btw., the ChangeLog entry for Jan's patch was riddled with typos and
wrong pathnames. I've corrected that with a separate checkin.

* lib/gcc-dg.exp (GCC_UNDER_TEST): Set before calling
check_linker_plugin_available.
