+qemu-i386 fails on system(3) with a cross-toolchain from Buildroot
+
+qemu-i386 fails with small C program containing a system().
+The C program is cross-compiled with a toolchain created by buildroot (http://buildroot.net/), gcc version 4.6.3, uClibc version 0.9.33.2 .
+qemu version 1.2.0 (built with http://git.buildroot.net/buildroot/tree/package/qemu/qemu.mk)
+host machine : Ubuntu 12.04 LTS on x86_64.
