Subject: [PATCH] Don't link against openssl directly
This patch changes our build process to no longer link against
openssl directly but instead rely on postgres linking it.
Linking to openssl directly is causing problems when the openssl
version we link against does not match the version postgres links
against. While this is easy to prevent where we fully control the
build process it is repeatedly causing problems e.g. in ABI tests.
This patch changes only changes the behaviour for non-Windows as
we are running into linker problems on Windows with this change.
Until we can find a workaround for those problems Windows binaries
we still link OpenSSL directly.
