Subject: [PATCH] openvswitch: add target perl handling

Allow the build to specify a path for the perl instead of reusing
the PERL variable which can lead to inconsistencies if we are cross
compiling. The TARGET_PERL variable will be used for script
substitutions to ensure the scripts will be able to properly execute
if the target system has a different path for the perl.
