* add support for mingw32
* Engines are installed in a slightly different path, which is
  urgly, patch it to make the path shorter
* remove runtime dependency from perl for mingw nativesdk

since commit 70da1f956bfbb627691c47eba7451182aca758e3 of oe-core
'openssl: Add c_rehash to misc package and add perl runtime dependency'

package openssl-misc have runtime dependency on perl, and perl then
have depenency on another 3 recipes, db/gdbm/libxcrypt. according to
http://arsv.github.io/perl-cross/usage.html, perl don't support
cross-compile build for mingw32 and another 3 recipes also don't
support mingw well. so remove the dependency of perl, don't support
c_rehash for mingw.
