maxima: enable sbcl option only on supported archs
https://github.com/void-linux/void-packages/pull/37608

Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **NO** (only build tested)

@tornaria not having sbcl support in maxima on some archs might break sagemath (?), but this is an overall improvement, the maxima package wasn't built at all for cross archs (arm, ~~ppc~~)
<!--
