Patch

libs/gst/helpers/Makefile.am has a install hook which can cause install races
and thus errors:

| /usr/bin/install: cannot create regular file
`/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-qa-pam/build/build/tmp/work/core2-64-poky-linux/gstreamer1.0/1.6.1-r0/image/usr/lib/gstreamer1.0/gstreamer-1.0/gst-plugin-scanner':
File exists

This needs to be a install-data-hook not an install-exec-hook as the helpers
are
installed into helperdir which is considered data (only path variables with
"exec" in are considered executables).

http://www.gnu.org/software/automake/manual/html_node/The-Two-Parts-of-Install.html#The-Two-Parts-of-Install

The explicit dependency on install-helpersPROGRAMS was an attempt at solving
this, but this causes occasional races where install-helpersPROGRAMS can run
twice in parallel (once via install-all, once via the hook's dependency).
