Subject: [PATCH 3/3] tools/perf: build fixes for arch_errno_names.sh

Allow the CC compiler to accept a CFLAGS environment variable.
Make the architecture test directory agree with the code comment.
This doesn't change the code generated but makes it easier to integrate
running the shell script in build systems like bazel.
