It mostly looks good, and I almost applied, but I do have a few
questions/comments.

Could you explain why a target variant of this package is needed? What
are the use cases for having those tools installed on the target?

You need:

	select BR2_PACKAGE_OPENSSL
	select BR2_PACKAGE_ZLIB

also, could you:

 (1) Verify that it builds with the basic OpenSSL options, i.e after
     disabling all openssl sub-options ?

 (2) Verify that it builds with libressl ?

Note: do *not* add any "select" here.

Use "openssl" instead of "libopenssl".

Use "host-openssl" instead of "host-libopenssl".

Thanks a lot!
