[committed] Fix gnu23-builtins-no-dfp
Last patch for the night. There's still a bit of minor fallout left in GCC
(loongarch testsuite for example). But things are looking good on the targets
I test. The plan is to start submitting the various newlib/libgloss fixes
tomorrow.
Anyway, this test was the one I was most concerned about. Basically we're
testing that on a !dfp target that the builtins are not available. It expects
a warning, but gets an error by default now. I just changed the test to use
-fpermissive, so that the test behaves as it did previously.
Pushed to the trunk.

* gcc.dg/gnu23-builtins-no-dfp-1.c: Add -fpermissive.
