compiler/gfortran.mk

[Jason Bacon <outpaddling%yahoo.com@localhost>]

Is there a reason the default version is unconditionally hard-coded at 4.8?

GFORTRAN_VERSION?=      48

Seems to me it would be better to match the base compiler (e.g. 5.5 on 
NetBSD 8.1).

I can override it in etc/mk.conf of course, but maybe this is something 
that could use some attention?
