Unbreak gcc options checking
Commit c810a0aca3f1148d2072d44b91b8cc9caeb4cf19 changed the gcc flag
test to include a call to alloca() which at least on GCC 6.2 just
causes all the tests to fail with implicit declaration warnings
which are errors since we test with -Werror. Include <alloca.h>
to avoid the warnings and thus make the test functional again.
