From b4df526ce37bced5be76f40c880de83f4fb23e7b Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Fri, 5 Mar 2021 14:48:38 +0100 Subject: [PATCH] package/openblas: respect the optimization level specified by Buildroot openblas internally sets -O2, after the flags being passed by Buildroot (e.g. -Os). Patch openblas to let the Buildroot-specified flag survive.
