Comment (by raimue):

 I see no downsides of using a shared directory for all gcc ports. The only
 change would be that a `port clean` would produce a warning about other
 distfiles in this directory, but the warning is harmless:

 {{{
 $ sudo port clean --dist gcc6
 --->  Cleaning gcc6
 Warning: Distfiles directory '/opt/local/var/macports/distfiles/gcc' may
 contain distfiles needed for other ports, use the -f flag to force removal
 }}}
