Issues building on ppc-64

I hit the following issue trying to build dale on linux-ppc64 on a POWER9 machine.
LLVM ERROR: Cannot select: 0xebcb7a4140: ch = store<(store 10, align 16)> 0xebcb7a3fa0, 0xebcb7a3e00, 0xebcb7a4278, undef:i64

Happy to provide SSH access to a POWER9 machine if needed.

This should be fine now (see the gh-216 branch). Tested on an S922 (CentOS Stream 8) on IBM Cloud.
