Subject: Add -fno-builtin to CFLAGS when building integration tests
References: boo#1240665, https://github.com/jemalloc/jemalloc/issues/2823
Upstream: tbd

GCC 15 optimizes out allocations which aligned_alloc integration test
expects to fail.  Using the -fno-builtin option prevents GCC from
treating malloc specially in this way and the test-suite to pass.
