File skiboot-build-LDFLAGS-pass-pie-flag-explicitly-to-ld.patch of Package qemu.12241
From d150a119e3721e634ca31f0ec255add7b955a56d Mon Sep 17 00:00:00 2001 From: Nicholas Piggin <npiggin@gmail.com> Date: Tue, 18 Jul 2017 20:40:06 +1000 Subject: [PATCH] build: LDFLAGS pass -pie flag explicitly to ld When building with some toolchains, the gcc -pie option does not enable the linker pie without explicitly passing it to ld, resulting in a non-PIE binary that silently fails (due to relocation failure). This was observed with the powerpc64le cross compiler for Debian. Pass -Wl,-pie explicitly, which allows the powerpc64le toolchain to create a position independnet binary that boots.
