Update to 2.11. From the changelog:

* "append" causes appends array exports from multiple searches using
  the same variable to append (vs. overwrite) their values. default
  is old behavior (i.e., "noappend" which overwrites).

* "scalar" seems to work; update POD so that people know to use it.

Updating during the freeze because it's nearly a leaf, and the only
depending package (p5-Test-BDD-Cucumber) still passes its self-tests.
Updated devel/p5-FindBin-libs to 2.11
