> Although this would fix the issue in the tree, a number of ports explicitly call the __sync_* builtins, including some that have USE_GCC set, so even fixing clang would not address this.

Do we know how many ports there are that do this? This only affects
ports that use __sync_*, have USE_GCC is set and are being built on
ARMv5.

I think our intent should not be to "keep compilers happy". FreeBSD
should provide proper APIs instead (e.g. <stdatomic.h>).
