Since Revision 1.97, CVS_RSH is unconditionally set to override settings from the CVS packages' environment. This, however, broke automated builds, since that environment variable also communicated their pubkey-authenticated SSH variant. Introduced two ways to remedy that:
1. Take JW_BUILD_SSH from the environment which takes precendence over everything else. 2. Made JW_BUILD_SSH_EXTRA_OPTS a += assignment, to allow callers to squeeze extra options into the environment.
