Inherit inherits everything except for what you override, so your
package can be refered to as starpu-maxnodes1 when using it as an input
for another package (for example), but to build it from the command line
it still has the original name of "starpu".

Also, I haven't tried running 'guix build -m manifest.scm
package-in-manifest', so I don't know if that works or not.
