Keith Packard 62bc9bf3e5 cmake: Allow selection of libc API overflow detection mode ... This adds a choice of three different libc API buffer overflow detection modes: * None * Compile-time * Compile-time and Run-time These correspond with the clang/gcc _FORTIFY_SOURCE modes (0/1/2). _FORTIFY_SOURCE depends on compiler optimizations and require libc support which the minimal C library doesn't include, so _FORTIFY_SOURCE is disabled by default in those cases. Native tooling might also enable _FORTIFY_SOURCE, so don't enable it by default in that case either. Signed-off-by: Keith Packard <keithp@keithp.com>		2022-10-31 23:23:27 +09:00
