fix: ignore atomic primops on ARM architectures (GHC 8.8.3) (#857)
Fixes the #441 issue with GHC 8.8.3 (fix that was already applied to GHC 8.6.5 with PR #480).
Testing environment:
- GHC 8.8.3 (cross-compiler)
- NixOS 20.03
- Building host: x86_64
- Target host: armv6l
Without this PR, the symbol `__sync_val_compare_and_swap_8` was not found by `remote-iserv` as described in #441 but this time with GHC 8.8.3. The 8.6.5 patch also works for 8.8.3. Perhaps it would be preferable to apply this patch to a range of GHC versions rather than specific versions, but I have only tested it and verified that it works properly on those specific versions.
I have not submitted this patch to the GHC GitLab as I haven't encountered any problem building a cross-compiling version of GHC from there.
