When building foot with pgo under gentoo's portage, LLVM tried to generate profile data files directly under system root, triggering sandbox violation and causing build to fail. Setting this envvar fixes the issue by explicitly specifying profiling data location. Reference: https://clang.llvm.org/docs/UsersManual.html#profiling-with-instrumentation
