not page aligned. To do this, use the ld script gnu ld installs on my
system.
This is imperfect: LDFLAGS_BIN and LD_FLAGS_BIN describe different
things. The loader script could be better named and take into account
other architectures. And having two different mechanisms to do
basically the same thing needs study. However, it's blocking forward
progress on lld, so I'll work in parallel to sort these out.

Go ahead and defined -D_STANDALONE for all targets (only strictly
needed for some architecture, but harmless on those it isn't required
for). Also add -msoft-float to all architectures uniformly rather
that higgley piggley like it is today.

- 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.
