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.

It would appear that some or all of this patch is unnecessary. OE-core 166bb89f6d97495b6522786182b4f9623acd7ff4 implements part of this patch, which makes me think it's working there without any changes necessary. It would be worth following up to see if that is the case.
