This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'

floating point instructions if it detects support at runtime. Make it also

Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.
This makes /lib being populated again.

MACHINE_CPUARCH or MACHINE_ARCH, not MACHINE. The latter is for kernel
only things. Also, I think this should be unconditional since all our
architectures have long double support, but I don't have time to test
that thoroughly so just add a comment to that effect.
The conditional came from NetBSD, where only select architectures have this
header/support
All architectures on FreeBSD have the necessary support though, so the
conditional's completely unnecessary

changes to add kernel and userland support will be committed as they are
reviewed.
As our copy of binutils is too old the devel/aarch64-binutils port needs
to be installed to pull in a linker.
To build either TARGET needs to be set to arm64, or TARGET_ARCH set to
aarch64. The latter is set so uname -p will return aarch64 as existing
third party software expects this.

The C11 standard introduced a set of macros (CMPLX, CMPLXF, CMPLXL) that
can be used to construct complex numbers from a pair of real and
imaginary numbers. Unfortunately, they require some compiler support,
which is why we only define them for Clang and GCC>=4.7.
The cpack() function in libm performs the same task as CMPLX(), but
cannot be used to generate compile-time constants. This means that all
invocations of cpack() can safely be replaced by C11's CMPLX(). To keep
the code building with GCC 4.2, provide copies of CMPLX() that can at
least be used to generate run-time complex numbers.
This makes it easier to build some of the functions outside of libm.

While here, remove the explicit cast of 0.25 to float. Replace
a multiplication involving 0.25 by a division using an integer
constant 4. Make a similar change in j0() to minimize the diff.
