fbgemm_avx512 build failure
Labels: module: build, triaged

### 🐛 Describe the bug

I'm building git master with the [same Arch recipe](https://raw.githubusercontent.com/archlinux/svntogit-community/packages/python-pytorch/trunk/PKGBUILD).

My CPU is Ryzen 2 and does NOT support AVX-512. fbgemm is programmed wrongly and demands `fbgemm_avx512` even when the main project has disabled it:
