Before the change `pkgsMusl.adobe-reader` was failing the interpreter:
$ nix-instantiate --eval --strict --expr 'with import ./. {}; builtins.tryEval pkgsMusl.adobe-reader'
error:
error: evaluation aborted with the following error message: 'unsupported platform for the pure Linux stdenv'
After the change `pkgsMusl.adobe-reader` returns catchable excation:
$ nix-instantiate --eval --strict --expr 'with import ./. {}; builtins.tryEval pkgsMusl.adobe-reader'
{ success = false; value = false; }
Noticed when was exploring `nixpkgs` for uncatchable evaluation errors.
Ideally those should only happen when there is a code bug in the use
site. In this case it's just a package with incompatible constraints for
`musl`.
Changed uncatchable `abort` to `throw`.
