Can't run binary outside of project directory.

[TwoClocks]

if you copy the arocc bin and a c file out of the project directory, it fails with
fatal error: unable to find Aro builtin headers

It looks like Complation.defineSystemIncludes walks the file system from the binary upwards, looking for include/stddef.h. So if you move the binary outside the project tree... no bueno.

With some guidance, I can take a stab at it. Do you want to just embed the file(s), or add a build step to compress them first? or other?

GCC fails with gcc: fatal error: cannot execute ‘cc1’: execvp: No such file or directory when moved out of installation directory and clang ignores the failure so that you get an error when trying to include stdalign.h for example.

Based on that the current behavior is fine but if you want this to work then you can just make that a non-fatal error.
