From 1726368b533d884c7ba2c63d047b3f3a015a7e49 Mon Sep 17 00:00:00 2001 From: Sam James Date: Thu, 10 Jul 2025 05:34:40 +0100 Subject: [PATCH] sci-libs/openblas: fix cross for arm64, ppc64 Borrow what conda forge does. I've tried to be careful and only do it for cross especially given the build system seems pretty brittle here.
