The variable switches the default type for add_library from STATIC to SHARED. We can condition additional stuff on that for convenience. (tabtest still doesn't build.) BoringSSL as any kind of stable system shared library is still very much unsupported, but this is probably handy for making sure we don't forget all those pesky OPENSSL_EXPORTs.
