If I apply just this patch, then the libressl package can be enabled at
the same time as the openssl package, with one overwriting the files
installed by the other.

So I think we need to introduce the virtual package first, with openssl
as the only provider, and then add libressl.

A bit weird. Why does their ltmain.sh differs from other ltmain.sh
generated by libtool 2.4 ?

Another question is how do we handle the host package. Right now, all
packages that need openssl on the host depend on host-openssl. So as it
is, this host-libressl package is never used.
