set-rpath-library.sh test failure w/musl

[dtzWill]

Test skipped in nixpkgs expression when using musl as a result:

NixOS/nixpkgs@c0d343b

Here's the build log, FWIW:

https://gist.github.com/dtzWill/3852581fceca47f2680e2c5890159659

LMK if any additional details or help reproducing would be useful.

The following reproduces the problem (although you may need to build a musl stdenv first :3)

$ $ nix build -f https://github.com/dtzWill/nixpkgs/archive/patchelf-unstable-musl-repro.tar.gz patchelfUnstable --arg localSystem '{config="x86_64-unknown-linux-musl";}'

Fixed in #104 and hope to catch these early in #205
