Add freebsd-gcc6 port.

This port is basically identical to the existing <arch>-gcc ports
that use GCC6.  However, it uses flavors for the different
architectures instead of slave ports.  It also includes the external
toolchain makefile and thus subsumes the <arch>-xtoolchain-gcc
port into the new packages.

This should permit us to have ports for different major versions of
GCC (e.g. a freebsd-gcc9 port).

aarch64-gcc6 disables LTO support to work with aaarch64-binutils
which builds a static ld.bfd binary by default which is unable to work
with LTO.
