#### Testing the changes
- I tested the changes in this PR: **briefly**

<!--
#### New package
- This new package conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements): **YES**|**NO**
-->

<!-- Note: If the build is likely to take more than 2 hours, please add ci skip tag as described in
https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration
and test at least one native build and, if supported, at least one cross build.
Ignore this section if this PR is not skipping CI.

<!--
#### Local build testing
- I built this PR locally for my native architecture, (ARCH-LIBC)
- I built this PR locally for these architectures (if supported. mark crossbuilds):
  - aarch64-musl
  - armv7l
  - armv6l-musl
-->

I don't think there's any reason to ship the full and the reduced versions in the same package, so I just compile the full one and create symlinks for compatibility.

#### TODO:

- [x] fix musl: ~~it uses some functions requiring `_GNU_SOURCE`, but other parts of the source define it without checking if it's already defined, so I get compilation errors if I just define it globally.~~
- [ ] build with assembly where possible: on i686 and x86_64* it requires `asmc` or `jwasm`/`uasm` assemblers, none of which are packaged
- [x] build a version with RAR support (nonfree repo)
- [x] use our compile and link flags
- [ ] what's the most appropriate name for the package? 7zip, 7-zip or 7z?
- test packages that depend on `p7zip` at runtime or build time:
    - [ ] julia
    - [ ] lutris
    - [ ] multibootusb
    - [ ] playonlinux
    - [ ] SLADE
    - [ ] Z80Explorer
    - [ ] ark
    - [ ] cbp2make
