[Buildroot] [PATCH v2 1/2] package/cryptopp: add a blind Config.in.host

[Carlos Santos <casantos@datacom.com.br>]

Quoting Thomas Petazzoni, the idea we have for the future is:

 * All host packages have a Config.in.host option.

 * The host packages that are only build dependencies of other packages
   have a blind Config.in.host option

 * The host packages that are useful by themselves continue to have a
   visible Config.in.host option.

host-cryptopp gets a blind Config.in.host, since only exists to build
tegrarcm. A help text is included to document the package, only, since
it is not shown in the configuration menu.
