By default, the gcc compiler built by Yocto is not configured with plug-in 
support.

To resolve this, I added a bbappend file for the gcc-cross recipe in my custom 
layer, which simply contained:

EXTRA_OECONF += "--enable-plugin"

This added the "--enable-plugin" flag to the do_configure task when 
configuring/building the gcc-cross compiler.

Note:  Where you add the "--enable-plugin" configure option will depend on 
which compiler needs plugin support.
