Is this a bug/limitation in glibc's actual code, or in glibc's build
environment?
Asked another (wordier) way -- should I understand -- assuming nobody
adds some explicit -fno-stack-protector to the non-hardened profiles
or the glibc ebuild -- and, of course, also that the user has not put
it in make.conf or similar -- that this would break glibc compilation
in the base configurations of the x86/amd64 non-hardened profiles?*
If that's so... that doesn't sound so great, does it?
Just thinking out loud, I guess, but, the fact -- if it is, indeed,
still a fact (?) -- that, as of gcc-4.8.2, putting -fstack-protector
in your CFLAGS breaks glibc.ebuild doesn't /necessarily/ mean that, as
of gcc-4.8.3, leaving -fno-stack-protector out of your cflags would
also break it, even if they are supposed to mean the same thing --
that would depend on the specific etiology of the problem.
Sorry, perhaps Google Search would answer my question as readily as
portage, in which case, by all means feel free to "lmgtfy" my ass.
But if nobody knows the answer for sure, presumably you have the means
to find out, Ryan?
If for any reason you need a guinea-pig, I have a non-hardened
triple-multilib (but mostly ABI_X86="64 32") workstation, here, that
I'm not afraid to break.
