Build a 32-bit EFI loader on amd64. This to match the rest of the code that is used to construct a loader (e.g. libstand, ficl, etc). There is such a thing as a 64-bit EFI application, but it's not as standard as 32-bit is. Let's make the 32-bit functional (as in we can load and actualy boot a kernel) before solving the 64-bit loader problem. 2012-04-20 15:01:23 +00:00			`.if ${MACHINE_CPUARCH} == "amd64"`

Enable GCC stack protection (aka Propolice) for userland: - It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.
