Don't forget that an openssl provider can be provided by a br2-external
tree. If we force the condition to BR2_PACKAGE_LIBOPENSSL, then it
prevents any such provider to be used.
So, I think the best solution is to exclude libressl, rather than limit
to libopenssl. I've tried to come up with a simple conditional block:
# An openssl provider is needed, but libressl is no match.
# A provider from a br2-external is supposed to match.
ifeq ($(BR2_PACKAGE_OPENSSL),y)
ifeq ($(BR2_PACKAGE_LIBRESSL),)
LIBKRB5_SSL = y
endif
endif
ifeq ($(LIBKRB5_SSL),y)
LIBKRB5_DEPENDENCIES += openssl
LIBKRB5_CONF_OPTS += \
--enable-pkinit \
...
endif
