The idea was not to remove that example altogether, but update it 
to use a newer version.

A simplified version of the commit looks as follows:

  -#   USE_GCC=   7+                      # port requires GCC 7 or later.
  +#   USE_GCC=   9+                      # port requires GCC 9 or later.

The other example that referred to GCC 6 was mandatory to update since
USE_GCC=6 is not supported any more; version 7 I could have left in, but 
figured pointing people to something newer would be better.  

In general the USE_GCC=X+ is mostly used for ports newer than the current
default.  Just with GCC_DEFAULT at 9, which is the newest release available,
that was the highest choice available - until GCC 10 becomes available in
spring. ;-)

Would you prefer different examples in Mk/bsd.gcc.mk?
