Reduce libstand Makefile duplication

Userboot's copy of the libstand Makefile had more extensive changes
compared to the one in sys/boot/libstand32, but it turns out these are
not intentional and we can just include lib/libstand/Makefile as done
for libstand32 in r293040.

Use CFLAGS_NO_SIMD in preference to varying lists of -mno-xxxx flags.
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.

Reduce diffs between the three copies of libstand's Makefile

This should be a non-functional change. A future change should
address the functional differences between these three and converge
on a single source.

sys/boot/userboot/libstand/libstand.a should also include strtoul.c;
as lib/libstand/ and sys/boot/libstand32/ already does.

Remove ia64.

This includes:
o All directories named *ia64*
o All files named *ia64*
o All ia64-specific code guarded by __ia64__
o All ia64-specific makefile logic
o Mention of ia64 in comments and documentation

This excludes:
o Everything under contrib/
o Everything under crypto/
o sys/xen/interface
o sys/sys/elf_common.h

Spell NO_PROFILE= as MK_PROFILE=no.

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

For libstand and sys/boot, split off gcc-only flags into CFLAGS.gcc.

Use MK_SSP=no after including bsd.own.mk to disable SSP instead of user-knob
WITH[OUT]_SSP to avoid hitting an error if user has WITH_SSP in their
make.conf. Ports now use this knob.

make[7]: "/usr/src/share/mk/bsd.own.mk" line 466: WITH_SSP and
WITHOUT_SSP can't both be set.

This is similar to previous cleanup done in r188895

Merge index() and strchr() together.

As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.

Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.

Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().

This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.

Add a version of the FreeBSD bootloader which can run in userland, packaged
as a shared library. This is intended to be used by BHyVe to load FreeBSD
kernels into new virtual machines.
