limits-fndefn.c takes an impressively long time to run.   On an idle
machine, -O3 -g -c takes 17:31 and -O2 -g -c takes   The test already
has a dg-timeout-factor of 4 giving a total timeout of 20 minutes.

Removing the -g brings this down to 30 s.  Keeping the -g and adding
-fno-var-tracking brings this down to 45 s.

We could bump the multiplier up to 8 but it's getting a bit
ridiculous.  Any thoughts?
