Request: Warning for lack of appropriate compiler

I recently tried to compile an app using
```
PackageCompiler.create_app(package_dir, target_dir, force = true, precompile_execution_file = build_dir * "/generate_precompile.jl")
```
but without loading an appropriate version of gcc. After creating the system image, I got several hundred lines of errors. I can't include it all (too long for a Issue boy apparently), but here's a sampling:

Expand for output

but the root cause of all this wasn't clear to me. Perhaps `create_app` could check if an appropriate gcc version is loaded before creating the sysimage and throw a clear error if not.

Happy to provide more details about my case if needed.

Start at PackageCompiler.create_app and the system-image compilation path that invokes embedding_wrapper.c; review how the compiler is selected before the shown C-header errors occur. Done means an unsuitable compiler is detected early and a useful warning is emitted instead of leaving users to discover the failure in the generated output.
