I found that instantiating xbursttools brought to the openssl evaluation

throwing an exception about an undefined platform.openssl.system.

That was introduced by r31330, which made openssl for the build system to
evaluate the platform.openssl.system, that should only be needed for the host
system.

I also revert supplying openssl.system for xbursttools.
