Make "shared" builds the default

In most cases we expect that people will be using shared libraries not
static ones, therefore we make that the default.

      All of these option have not worked for some while and are fundamental

  Note on shared libraries
  ------------------------
 
- Shared libraries have certain caveats.  Binary backward compatibility
- can't be guaranteed before OpenSSL version 1.0.  The only reason to
- use them would be to conserve memory on systems where several programs
- are using OpenSSL.
-
- For most systems, the OpenSSL Configure script knows what is needed to
- build shared libraries for libcrypto and libssl.  On these systems,
- the shared libraries are currently not created by default, but giving
- the option "shared" will get them created.
+ For most systems the OpenSSL Configure script knows what is needed to
+ build shared libraries for libcrypto and libssl. On these systems
+ the shared libraries will be created by default. This can be suppressed and
+ only static libraries created by using the "no-shared" option. On systems
+ where OpenSSL does not know how to build shared libraries the "no-shared"
+ option will be forced and only static libraries will be created.
