Heroku build fails but continues and succeeds anyways. (Bug Report)

crystal -v = 1.10.1

Building on Heroku gracefully fails but still succeeds at compilation. Happens between shards install and shards build.

@noraj FWIW, you don't need to cross compile at all. Given the only arch you support is x86_64, you can just run shards build --release --no-debug --static in the alpine image and the resulting binary can be used with both musl and glibc.
