Disable -Wstringop-overflow in --enable-optimized builds with GCC
This reverts commit e287fde52fb9de5bdf1d00c8a3fbfcca7db9892c "Silence bogus
-Wstringop-overflow with GCC trunk towards GCC 10", as that workaround, which
happened to work for some revisions of GCC trunk towards GCC 10, no longer works
for GCC 10 release candidates, see
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92893#c9> "[10 Regression]
Unhelpful -Wstringop-overflow warning for a trailing one-element array".
(Using -Wstringop-overflow=1 instead of the -Wstringop-overflow=2 default would
have still caused bogus warnings, requiring -Wno-stringop-overflow.)
