4dc607e7f2 Integrate a number of testcases from tools/regression/lib/msun
into the FreeBSD test suite

There's no functional change with these testcases; they're purposely
being left in TAP format for the time being

Other testcases which crash on amd64/i386 as-is have not been
integrated yet (they need to be retested on a later version of
CURRENT, as I haven't used i386 in some time)

1fdcc5e5c0 Start support for the RISC-V 64-bit architecture developed by UC Berkeley.
RISC-V is a new ISA designed to support computer research and education, and
is now become a standard open architecture for industry implementations.

This is a minimal set of changes required to run 'make kernel-toolchain'
using external (GNU) toolchain.

7b3ea376a2 META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.
This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

cbc120b22c Fix compilation when the armv6 world is being compiled without hw floating
point support.  The fenv-vfp.c file overrides -mfloat-abi so it can use
floating point instructions if it detects support at runtime.  Make it also
override -mfpu in case the user has set -mfpu=none.

c6b992ed3a The presence/absence of CPU features should be tested with
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.

8daa81674e Start to import support for the AArch64 architecture from ARM. This change
only adds support for kernel-toolchain, however it is expected further
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.

2cec876a59 Rename cpack*() to CMPLX*().
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.
