| In simple-chrome, clang is a shell wrapper, it calls clang.elf, which is the |
| real binary, then, clang.elf calls clang.elf itself. It is the last invocation |
| "clang.elf -> clang.elf" that breaks, because direct calls to clang.elf misses |
| all environment setup in clang wrapper. Fix this by calling to clang wrapper |
| instead of clang.elf binary. |
