Add gems for ECC algorithm support.

These definitions have been added to resolve build issues with ECC
algorithm support.

The bcyrpt_pbkdf gem currently link against shared libs which are not
installed on Cisco IOS-XR.

The rbnacl-libsodium gem currently fails to compile on Solaris for both
x86-64 and SPARC architectures.

Adding these definitions will allow us to selectively define the
supported platforms as well as provide a simple means to itterate on
patches as needed.
