Subject: [PATCH] perl: 5.8.7 -> 5.8.8 (from OE)

Upstream-Status: Inappropriate [embedded specific]

Allow the location that .so files are searched for for dynamic
loading to be changed via an environment variable. This is to allow
us to load .so's from the host system while building for the target
system.
