Patch 1/2 is a restructuring of the tests so that it is easier to add different configurations to _FORTIFY_SOURCE tests at various levels. Tested on x86_64 to confirm that there were no new regressions due to this and that the new tests also run clean. Changes from v1: - Rebased against latest trunk so that the patches actually apply. - Renamed files so that the diffs are easier to compare and also make a bit more sense. Changes from v2: - Renamed tst-chk-0.c to tst-fortify.c and autogenerate all tests and include it. - Set all the flags we can as -D in CFLAGS and autogenerate test cases if needed. - Fix other review comments.
