Subject: [PATCH v2 5/8] tools/nolibc: tests: fold in no-stack-protector
 cflags

For the cflags to enable stack protectors to work properly they need to
be specified after -fno-stack-protector.

To do this fold all cflags into a single variable and move
-fno-stack-protector before the arch-specific cflags.
