+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.

+    $ cat sys.c
+    #include <stdio.h>
+    #include <stdlib.h>
+
+    int main()
+   {
+    	int ret = system("echo hello");
+    	printf("%d\n", ret);
+    }

+    $ ../../host/usr/bin/i686-buildroot-linux-uclibc-gcc -o sys sys.c
+    $ file sys

+same problem with x86_64 :
+    $ ../../host/usr/bin/x86_64-buildroot-linux-uclibc-gcc -o sys sys.c
+    $ file sys
+    sys: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), not stripped

+works fine with arm :
+    $ ../../host/usr/bin/arm-buildroot-linux-uclibcgnueabi-gcc -o sys sys.c
+    $ file sys
+    sys: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
+    $ ../../host/usr/bin/qemu-arm ./sys
+    hello

+
+works fine with mips :
+    $ ../../host/usr/bin/mips-buildroot-linux-uclibc-gcc -o sys sys.c
+    $ file sys
+    sys: ELF 32-bit MSB executable, MIPS, MIPS32 rel2 version 1 (SYSV), dynamically linked (uses shared libs), with unknown capability 0x41000000 = 0xf676e75, with unknown capability 0x10000 = 0x70403, not stripped

+
+Looks like the long-standing "clone/fork for i386 user mode targets doesn't work" issue. See also discussion in bug 739785...
+
+
+Fixed in 2013 some time.
