Now that the libstdc++ testsuite is run with -ftrack-macro-location by
default, this patch triggers the -Wunused-local-typedefs warning when
-Wunused (and -Wall) is turned on.

The patch has been reviewed and accepted[1] a while ago, but was waiting
for the -ftrack-macro-expansion work to go in first.

Bootstrapped and tested again on x86_64-unknown-linux-gnu against
trunk.

Applied to the mainline.
