From b8d9a064f08614ac6f6b0ec26eab1450cf8b7544 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Fri, 9 Mar 2018 12:19:37 +0100 Subject: [PATCH] busybox: remove i386-specific build flags busybox tries to be smart and passes a number of additional flags to the compiler. Unfortunately, the i386-specific flags break ABI compatiblity with libc. Fixes busybox crashes observed on x86-generic with GCC 7.
