<!--
#### 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
- [ ] ~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
- [x] test packages that depend on `p7zip` at build/check time: SLADE, Z80Explorer, ark, cbp2make. (I just tested that they still build)
- test packages that depend on `p7zip` at run time:
    - [ ] lutris
    - [ ] multibootusb
    - [ ] playonlinux
