[Xen-devel] [PATCH] firmware/shim : filter output files during Xen tree setup

[Christopher Clark <christopher.w.clark@xxxxxxxxx>]

Exclude named output files from the Xen tree setup.

The linkfarm.stamp content will differ between top level "make"
and "make install" invocations, due to the introduction of these
output files that are produced during the "make" build.

Filter these out to prevent an unnecessary rebuild of the shim during
"make install".
