gnu: cross-base: Standardize API to use keyword arguments.

Browse source 
This makes it possible to invoke the procedures with a single or fewer
optional arguments.

* gnu/packages/cross-base.scm (contains-keyword?): New procedure.
(cross-binutils): Dispatch to either...
(cross-binutils/deprecated): ... this renamed procedure or ...
(cross-binutils*): ... this new procedure.
(cross-kernel-headers, cross-libc/deprecated): Likewise.
