### Eclipse Workspace Patch 1.0
#P lsvpd-new

Add ids file lookup to runtime.

Currently the pci.ids and usb.ids files are located by the Makefile
and the location defined by the build.  This presents a problem when
the build system has the files in a different location from the host.
This patch addresses this problem by moving the logic to locate the
ids files into the vpdupdate code.
