[Buildroot] [git commit] libv4l: properly error out when one of the make step fails

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=5c28f5956f7da25071303411c8fef308065f2887
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

In libv4l.mk, if there are multiple elements in $(LIBV4L_DIRS_y), they
are built in order, one after the other. However, our loop construct
doesn't take into account the fact that we should error out if one of
the steps failed.

A good illustration is having BR2_PACKAGE_LIBV4L_DECODE_TM6000 and
BR2_PACKAGE_LIBV4L_V4L2_CTL enabled. The build of decode-tm6000 will
fail, but the build will happily continue without stopping in libv4l.
