Hexagon compilation failure on ppc64le arch

[cimes-isi]

With PR #5558, I can build Halide v10.0.0, but recent changes may have broken the build on ppc64le, which I understand is not well-tested. I'm using a LLVM 11.0.0-rc1 module on a HPC system. I'm not sure if this is a build issue with the LLVM module that is appearing now due to a new dependency on LLVM features not previously used, or if this is actually an issue with recent Halide changes. Thanks.

[dsharletg]

I think the fix for this is #5503, I think the owner of that PR had the same issue.

[cimes-isi]

Thanks for the quick reply and the link. It looks like the author of that PR is waiting for feedback on his proposed approach(es). I've subscribed to the PR and obviously would also like to see a fix merged, esp. since we can't work around the issue with TARGET_HEXAGON=OFF.

[cimes-isi]

Thanks, I appear to have gotten past this error now and am encountering others. I'll open new issues for them.
