MFi386: revision 210387

Correctly setup LDADD with regards to libstand.

Reduce diffs against i386.

Fix build when WITH_SSP is set explicitly.

Submitted by: Jeremie Le Hen

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.

Don't unconditionally compile-in the bcache code. It's only used on
i386/amd64 and pc98. Remove useless calls to bcache_init() from the
ia64 and sparc64 loaders, as well as from the OFW common code.

Reimplementation of world/kernel build options. For details, see:

MFi386: revision 1.63.

Initiate deorbit burn of i386 a.out kld "support" in loader. Note that
this was quite broken, it never was updated for metadata support.
The a.out kld file support was never really used, as it wasn't necessary.
You could always load elf kld's, even in an a.out kernel.

-ffreestanding is the word.
(also resort some CFLAGS such that the more "important" value are first so
they are easier to see)
