By default, the gcc compiler built by Yocto is not configured with plug-in =
support.=0A=
=0A=
To resolve this, I added a bbappend file for the gcc-cross recipe in my cus=
tom layer, which simply contained:=0A=
=0A=
EXTRA_OECONF +=3D "--enable-plugin"=0A=
=0A=
This added the "--enable-plugin" flag to the do_configure task when configu=
ring/building the gcc-cross compiler.=0A=
=0A=
Note:  Where you add the "--enable-plugin" configure option will depend on =
which compiler needs plugin support.=0A=
