Changes v1 -> v2:
  * removed details from libssh2/Config.in (suggested by Arnout)
  * added libssh2 to select libgcrypt by default (suggested by Arnout)
  * fixed up configuration options libssh2 in libssh.mk 
    (suggested by Arnout)
  * removed removal of documentation and static libraries since the
    target finalize step takes care of this (suggested by Arnout)
  * added check for zlib dependancy
