Add patches to fix the build on FreeBSD 11 with libc++.

OpenVSP does something like this:
  using namespace std;
  class array {
    ...
  };

Which causes the build to fail with HEAD's libc++. Even though the port does
not use -std=c++11, libc++ still declares an array class that conflicts with
the one OpenVSP has.

Enclose OpenVSP's array declaration in a namespace to avoid these conflicts.
