non-working uClibc-ng build

This is a build of uClibc-ng that does not allow normal Linux booting.
You can boot to a shell by doing init=3D/bin/sh but any command you type (l=
ike
ls) would run the command and then crash the system because init (in fact t=
he
shell, the parent of the forked command) gets killed.

This might be related to issue in signal handling since the parent is suppo=
sed
to receive a SIGCHILD signal when its child exits.

Difference with previous attachment is just that the follow buildroot patch=
 is
not applied to gcc:
