[yocto] [meta-mingw] Patch needed to let linker find lto plugin

[winfried.dobbe at xmsnet.nl]

Hi Juro,

My Yocto environment is for the Congatec QMX6 SoM that is built around a 
quadcore i.MX6.
I use the Yocto layers from the Congatec repository 
(https://git.congatec.com/public), which includes the meta-fsl-arm and 
meta-fsl-arm-extra layers.

My bblayers.conf is:

BBLAYERS = " \
   ${BSPDIR}/sources/poky/meta \
   ${BSPDIR}/sources/poky/meta-poky \
   \
   ${BSPDIR}/sources/meta-openembedded/meta-oe \
   ${BSPDIR}/sources/meta-openembedded/meta-multimedia \
   ${BSPDIR}/sources/meta-openembedded/meta-python \
   ${BSPDIR}/sources/meta-openembedded/meta-networking \
   \
   ${BSPDIR}/sources/meta-fsl-arm \
   ${BSPDIR}/sources/meta-fsl-arm-extra \
   ${BSPDIR}/sources/meta-fsl-demos \
   \
   ${BSPDIR}/sources/meta-mingw \
   \
   ${BSPDIR}/sources/meta-peek \
   ${BSPDIR}/sources/meta-peek-ecng \
"

The image I normally build (peek-image-ecng-acu-default) is based upon 
the core-image-full-cmdline image.

I built the MinGW SDK by adding SDKMACHINE="x86_64-mingw32" to my 
local.conf and typing the command "bitbake peek-image-ecng-acu-default 
-c populate_sdk".

I attended the Yocto developer day in Berlin last week. When I showed 
the MinGW linker LTO plugin error to Mark Hatle, he suggested applying 
his patch.

best regards,

Winfried
