aarch64-binutils is no longer built static by default, so aarch64-gcc
can now enable LTO.

- Add --with-sysroot=/ to CONFIGURE_ARGS. base/binutils needs this so
that ld honors --sysroot in linker scripts. base/gcc6 needs this so
that the C++ include paths honor --sysroot.
- Remove a hack from GCC's configure to force C++98 mode when building
GCC with GCC. libc++ assumes C++11, so this hack was breaking the
build of base/gcc6 natively when the system compiler was GCC.
- Add toolchain makefiles installed to /usr/share/toolchains.
These are suitable to be used by CROSS_TOOLCHAIN when doing a native
arch build. These makefiles enable appropriate knobs so that the
in-tree components that are replaced by each package are not built
or installed. The freebsd-gcc toolchain makefile includes the
binutils toolchain makefile if it is present.

This is in preparation for adding a base/gcc9 port.
While here, update to GCC 6.5.0.
Share packing lists with the freebsd-gcc6 port as much as posible.
Split most of the freebsd-gcc6 pkg-plist into a pkg-plist.common that
lists arch-independent files under lib/. Change base/gcc6 to use the
arch-specific packing lists and pkg-list.common from freebsd-gcc6. In
addition, hook up packing lists for the remaining archs supported by
freebsd-gcc6 but not base/gcc6: aarch64 and sparc64.
