This broke the build with NO_OPENSSL=1, so Debian will need to revert
it:

I'll try a NO_OPENSSL build later on today and see to get it fixed.

Also, the Makefile already has a NEEDS_CRYPTO_WITH_SSL flag that’s
automatically set on Darwin, Windows, and MinGW.  We shouldn’t have two
mechanisms for addressing the same problem; maybe we just need to enable
the existing flag on more (or all) platforms?

No, these should be different issues; you may have a libssl (which uses
libcrypto) requiring libcrypto to be linked in, even if you only use
interfaces from libssl (and that's what NEEDS_CRYPTO_WITH_SSL seem to be
designed to deal with), but in this case what you have is rather
imap-send using the libcrypto interfaces _as well as_ the libssl
interfaces.

You are both correct; the point of NO_OPENSSL is not to link with anything
from openssl suite, so we need a separate mechanism to address this.

Anders, wouldn't this be a better fix for NO_OPENSSL build, than reverting
a fix for an incorrect ld invocation?
