Introduce an opt-in mode for building and running ZDTM static tests
with Guarded Control Stack (GCS) enabled on AArch64.
Changes:
- Support `GCS_ENABLE=1` builds, adding `-mbranch-protection=standard`
and `-z experimental-gcs=check` to CFLAGS/LDFLAGS.
- Export required GLIBC_TUNABLES at runtime via `TEST_ENV`.
- %.pid rules to prefix test binaries with `$(TEST_ENV)`
so the tunables are set when running tests.
- Makefile rules for selectively enabling GCS in tests
Usage:
# Build and run with GCS enabled
make -C zdtm/static GCS_ENABLE=1 posix_timers
GCS_ENABLE=1 ./zdtm.py run --keep-img=always \
-t zdtm/static/posix_timers
By default (`GCS_ENABLE` unset or 0), test builds and runs are
unchanged.
NOTE: This assumes that the test victim was compiled also using
GCS_ENABLE=1 so that the proper GCS AArch64 ELF headers are present
