insane.bbclass: Updated MicroBlaze machine definitions

* Removed existing definition with machine 47787, this
  definition is outdated, a sanity error should occur if an ELF uses this
  value.
* Added new definition with machine 189. This value replaces the existing
  value since August 2009. See binutils thread for more information.

gst-ffmpeg: fix --disable-yasm

The gst-ffmpeg build shows the following warning:

configure: WARNING: unrecognized options: --disable-yasm

which means that the following test in configure always fails and
--disable-yasm never gets passed to the embedded ffmpeg build:

'if test "x$disable_yasm" = "xyes"; then'
  embffmpeg_configure_args="$embffmpeg_configure_args --disable-yasm"

commit 4d309730 ['gst-ffmpeg: configure-fix patch used wrong test']
actually fixed the obviously backwards syntax by reversing the test -
prior to that, --disable-yasm would always unconditionally be passed
into the embedded ffmpeg config.

This fixes things so that the variable actually exists and makes the
test meaningful.

image.bbclass: fix postinstall intercepts fallback

The wrong type of paranthesis was used so 'continue' did nothing (was in
another context) and the packages were marked as installed.

gtk-update-icon-cache-native: create wrapper script

When using the sstate from another build machine, the path to the pixbuf
loader's cache points to a path on the remote machine. Hence, the update
of the icon cache fails on host.

smart: disable CHANNELSDIR

Make CHANNELSDIR in smart empty, since this causes host contamination issues
on some RPM-based hosts on which smart is already installed.
