From 5bce1721879bf125d9078671c5e499135b70c6b3 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Mon, 1 Sep 2014 22:06:06 +0200 Subject: [PATCH] uclibc: fix duplicate vfork problems when static linking Reported on uClibc mailinglist by Thomas Petazzoni Should fix: * SuperH http://autobuild.buildroot.org/results/a81/a810c2f27dee1978808461c05cbdcbf51a214e09/build-end.log * i386 http://autobuild.buildroot.org/results/f83/f83b65bfc6ea7c7406a02e92afda43e4c5db6e7c/build-end.log * x86-64 http://autobuild.buildroot.org/results/64f/64f418f54885e8b5093dc8949c2d1d1ff3c938ea/build-end.log * powerpc http://autobuild.buildroot.org/results/d5b/d5b7ac84dde0e4e26cd7cc46d79e66c39ed5cd53/build-end.log Tested with i386 static build of alsa-utils. Patch will be send to uClibc soon, need to finish test-suite run.
