Hum. But then it means that we have propagated the MMU dependency to
all reverse dependencies of openssl (i.e packages that depend on
openssl), but they may no longer need this dependency anymore.

There is a fairly huge list of packages that "select
BR2_PACKAGE_OPENSSL". How can we find out which ones will now build
fine without MMU support ?

By the way, do you have a specific need for openssl on no-MMU
platforms? If so, on which platform? We don't have many no-MMU users,
so it's good when they speak up :-)

Thanks,

Thomas
