Can't name executable the same as the package "linker command failed with exit code 1"

[BenjaminDoran]

Wanted to report so that others don't run into the same foot-gun. And make a tracking issue in case it can be fixed.

Linker error when binary is same as project. (using the quick-start test example)

% make app  
juliac \
        --output-exe appproject \
        --bundle build \
        --trim=safe \
        --experimental \
        AppProject

Linking works once the executable is renamed.
