[PATCH v5 0/2] _FORTIFY_SOURCE fixes [BZ #28746]

[Siddhesh Poyarekar]

The main patch is 2/2, which fixes some fortified headers to match
feature macros with their corresponding main headers, without which
functions would fail to get fortified.  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.

Changes from v3:
- Fixed typo (chk-gen-locals -> chk-gen-locales)

Changes from v4:
- Generate test sources in $(objpfx).
