[nolibc] Disable the GCC stack protector when building sanitizer runtimes.
This is the first in a sequence of changes designed to eliminate the libc dependency in sanitizer_common. The main motivation for these changes is to be able to provide an alternative for the current interceptor-based technique for instrumenting functions in libc. In this new technique, we compile libc with instrumentation. This has the potential advantages of being more accurate than interception and reducing the amount of custom code required for each libc function. As a side effect of this, we cannot depend on libc in the sanitizer runtime due to mutual dependency issues. This change disables the GCC stack protector, which introduces a libc dependency and is enabled by default in Ubuntu. Differential Revision: http://llvm-reviews.chandlerc.com/D755 llvm-svn: 181422
