+
+ SSP support has been added to ports with WITH_SSP for i386 and amd64
+ on FreeBSD 10, and amd64 on earlier versions.
+
+ SSP_UNSAFE is added to disable in a port if it fails to build, but
+ this should only be used in rare circumstances such as kernel modules.
+ Otherwise, the port may just be failing due to lack of respecting
+ LDFLAGS.
+
+ On FreeBSD 10, this uses an ldscript in /usr/lib/libc.so to pull in
+ libssp_nonshared.a to address issues linking on i386 [1].
+
+ On earlier FreeBSD versions the WITH_SSP knob will add -lssp_nonshared
+ to LDFLAGS on i386. This is not needed on amd64. However, several hundred
+ ports do not currently respect LDFLAGS, so this support is disabled currently
+ as it causes build failures if a dependency is looking for the stack_chk
+ symbols.
