I tried moving all the headers to
/usr/include/$(DEB_HOST_MULTIARCH)/openssl/ and rebuilding everything in
Ubuntu raring that build-depends on libssl-dev.  So far I've had 67
failures out of 428 attempts (there are still a few in progress), mostly
foolish configure scripts that try to manually detect the location of
the OpenSSL headers rather than letting the compiler work it out.  Now,
I think these are generally bugs, but this failure rate seems
inconveniently high to me; that's a lot of tedious fixing of (probably
mostly independent) build system bugs to do.  It would be nice not to
expose quite so many pre-existing bugs.

I'm currently trying the alternative of moving just opensslconf.h.  The
only things that should break with that are configure scripts (or
equivalent) that test for /usr/include/openssl/opensslconf.h directly; I
think this is probably rather rarer than configure scripts that test for
things like /usr/include/openssl/x509.h.
