maxima: dont default sbcl on aarch64, dont makedepends on emacs
https://github.com/void-linux/void-packages/pull/43311

Description:
@dkwo: try this.

 - Default to `~sbcl` for aarch64 since you say it's broken
 - Remove emacs from hostmakedepends; it seems the emacs support files don't really need emacs.

Let's see how this works. Note that your `maxima` package will not contain any binary, you will have to manually install `maxima-ecl`. If this is a good setup we can figure out how to address this. Not a problem for sagemath which depends on `maxima-ecl`.

For cross compiling, we would need to do something more fancy, i.e. an `ecl` binary that can cross-compile for aarch64. This is in principle possible as ecl compiles itself this way using the host ecl.
