The short version is that you can do something like this to use GCC
as the system compiler (/usr/bin/cc):

cd /usr/ports/base/binutils ; make install clean
cd ../gcc6 ; make install clean

Then 'make CROSS_TOOLCHAIN=freebsd-gcc6 buildworld', etc.  If you aren't
planning on doing cross-builds you can set CROSS_TOOLCHAIN in /etc/src.conf.

As described elsewhere, the base/* packages can be cross-built (along
with pkg), so for any architectures not yet using clang we could fairly
easily provide a cross-built package repo (though that architecture list
is becoming rather small).  I will probably add a base/gcc9 port once we
can build a full system with gcc9.
